प्रश्न 8.
रासायनिक अभिक्रिया के वेग पर प्रभाव डालने वाले कारकों का उल्लेख कीजिए। (1½)
उत्तर:
अभिक्रिया के वेग को प्रभावित करने वाले कारक अग्र हैं

  • सान्द्रण-अभिकारक की सान्द्रता बढ़ाने पर, अणुओं के आपस में टकराने की सम्भावना बढ़ जाती है फलस्वरूप अभिक्रिया का वेग बढ़ जाता है।
  • ताप-ताप बढ़ाने पर अणुओं की गतिज ऊर्जा बढ़ जाती है जिसके कारण उनकी आपस में टक्कर भी बढ़ जाती है और अभिक्रिया का वेग भी बढ़ जाता है।
  • दाब-दाब बढ़ाने पर गैसों के अणु पास-पास आ जाते हैं जिसके फलस्वरूप उनकी परस्पर टक्कर बढ़ जाती है फलतः अभिक्रिया का वेग भी बढ़ जाता है।
  • अभिकारकों का पृष्ठ क्षेत्रफलअभिकारकों का पृष्ठ क्षेत्रफल बढ़ाने पर भी अभिक्रिया का वेग बढ़ जाता है। उदाहरणार्थ, चूर्णित धातुओं में अभिक्रिया तीव्र गति से होती है।
  • अभिकारकों की प्रकृति-यदि अभिकारक आयनिक है तो उस अभिक्रिया का वेग अनायनिक अभिक्रियाओं की तुलना में अधिक होता है।

प्रश्न 9.
शून्य कोटि की अभिक्रिया से आप क्या समझते हैं? उदाहरण द्वारा समझाइए। इसके वेग स्थिरांक का व्यंजक लिखिए। (1½)
उत्तर:
शून्य कोटि की अभिक्रिया-वह अभिक्रिया जिसकी प्रगति में अभिकारक के किसी भी अणु का सान्द्रण परिवर्तित नहीं होता है अर्थात् जिसका वेग अभिकारक के सान्द्रण पर निर्भर नहीं करता है, शून्य कोटि की अभिक्रिया कहलाती है।
A → B + C
यदि इसका वेग ∝ [A]° हो, तो यह शून्य कोटि की अभिक्रिया होगी।

उदाहरणार्थ-सूर्य के प्रकाश की उपस्थिति में H, व Cl, का संयोग
RBSE 12th Chemistry Model Paper Set 4 with Answers in Hindi 7

शून्य कोटि के वेग स्थिरांक का व्यंजक-शून्य कोटि की अभिक्रिया के वेग स्थिरांक का व्यंजक x = kt है।
जहाँ X अभिकारक A की वह मात्रा है जो t समय में अभिक्रिया करती है और यह अभिक्रिया का वेग स्थिरांक है।

प्रश्न 10.
संक्रमण तत्त्व परिवर्ती ऑक्सीकरण अवस्था को प्रदर्शित करते हैं, क्यों? (1½)
उत्तर:
संक्रमण तत्त्वों का सामान्य इलेक्ट्रॉनिक विन्यास (n – 1)d1-10 ns1-2 हैं। (n-1)d-कक्षकों तथा ns-कक्षकों की ऊर्जाओं में अधिक अन्तर नहीं होता है अतः संक्रमण तत्त्वों में, (n-1)d तथा ns दोनों कक्षकों के आबन्ध निर्माण के लिए उपलब्ध रहती हैं। +1 तथा +2 ऑक्सीकरण अवस्थाओं में ns-कक्षकों के साथ (n – 1) d-इलेक्ट्रॉनों का भी योगदान होता है।

उत्तेजित अवस्था में (n – 1)dइलेक्ट्रॉन आबन्ध निर्माण में भाग लेने के लिए स्वतन्त्र हो जाते हैं तथा परमाणु विभिन्न ऑक्सीकरण अवस्थाएँ प्रदर्शित करने के योग्य हो जाता है। उदाहरण के लिए, Sc का बाह्य इलेक्ट्रॉनिक विन्साय 3d1 4s2 है। जब यह केवल 4s-इलेक्ट्रॉनों का उपयोग करता है। तो +2 ऑक्सीकरण अवस्था प्रदर्शित करता है, परन्तु जब यह दोनों 4s-इलेक्ट्रॉनों के साथ एक 3d-इलेक्ट्रॉन का भी उपयोग करता है तो +3 ऑक्सीकरण अवस्था प्रदर्शित करता है।

(ब) V2+ हेतु चुम्बकीय आघूर्ण का नाम परिकलित कीजिए।
उत्तर:
V2+ का इलेक्ट्रॉनिक विन्यास 3d होता है।
∴ अयुग्मित इलेक्ट्रॉनों की संख्या (n) = 3
चुम्बकीय आघूर्ण (μ) = \(\sqrt{n(n+2)}\)
= \(\sqrt{3(3+2)}=\sqrt{3 \times 5}\)
= 3.87 B.M.

प्रश्न 12.
निम्नलिखित रूपान्तरण सम्पन्न कीजिए : (¾ + ¾ = 1½)
(अ) प्रोपेनॉइक अम्ल से 2-ब्रोमोप्रोपेनॉइक अम्ल

RBSE 12th Chemistry Model Paper Set 4 with Answers in Hindi 9

प्रश्न 13.
कारण बताइए कि मेथॉक्सीमेथेन की तुलना में एथेनॉल का क्वथनांक उच्च होता है ? क्यों? (1½)
उत्तर:
एथेनॉल में विद्युत-ऋणात्मक ऑक्सीजन परमाणु से जुड़े हाइड्रोजन की उपस्थिति के कारण यहाँ अन्तरा-आण्विक हाइड्रोजन बन्ध उपस्थित होता है। इसके परिणामस्वरूप एथेनॉल संगुणित हो जाता है और इसके क्वथनांक का मान उच्च हो जाता है।
RBSE 12th Chemistry Model Paper Set 4 with Answers in Hindi 10
वहीं दूसरी ओर मेथॉक्सी मेथेन में कोई भी हाइड्रोजन आबन्ध नहीं होता। इस कारण इसका क्वथनांक निम्न होता है।

दीर्घ उत्तरीय प्रश्न

प्रश्न 16.
(अ) सक्रियण ऊर्जा क्या होती है? किसी अभिक्रिया का वेग सक्रियण ऊर्जा के मान को कैसे प्रभावित करता है?
(ब) A → B अभिक्रिया के लिए, अभिकारक की सांद्रता 0.05 M से 20 मिनट में परिवर्तित होकर 0.03 M हो जाती है। औसत वेग की गणना सेकंड तथा मिनट दोनों इकाइयों में कीजिए। (1½ + 1½ = 3)
अथवा
(अ) वेग स्थिरांक पर ताप का क्या प्रभाव पड़ता है? ताप के इस प्रभाव को मात्रात्मक रूप में कैसे प्रदर्शित कर सकते हैं?
(ब) एक प्रथम कोटि की अभिक्रिया में 25% वियोजन होने में 25 मिनट लगते हैं। की गणना कीजिए। (2 + 1 = 3)
[दिया गया है – log 2 = 0.3010, log 3 = 0.4771, log 4 = 0.6021]
उत्तर:
(अ) ऊर्जा अवरोध को पार करके उत्पाद बनाने के लिए देहली ऊर्जा से कम ऊर्जा युक्त अभिकारक अणुओं को जिंतनी ऊर्जा की और आवश्यकता होती है उसे अभिक्रिया की सक्रियण ऊर्जा कहते हैं।
अतः सक्रियण ऊर्जा = देहली ऊर्जा – अभिकारक अणुओं की औसत ऊर्जा
या Ea = Ethreshold – EReactants

प्रत्येक अभिक्रिया के लिए सक्रियण ऊर्जा का मान निश्चित होता है। किसी अभिक्रिया के लिए जब सक्रियण ऊर्जा का मान कम होता है तो अधिक संख्या में अणु ऊर्जा अवरोध को पार करके उत्पाद बना सकते हैं। इस प्रकार की अभिक्रियाओं के वेग अधिक होते हैं। सक्रियण ऊर्जा के उच्च मान युक्त अभिक्रियाओं के वेग कम होते हैं। अतः तीव्र अभिक्रियाओं के लिए सक्रियण ऊर्जा कम होती है। मन्द अभिक्रियाओं के लिए सक्रियण ऊर्जा अधिक होती है।

(ब) औसत वेग
RBSE 12th Chemistry Model Paper Set 4 with Answers in Hindi 14
औसत वेग = 0.001 mol L-1min-1
औसत वेग _ 0.001 mol L-1s-1
औसत वेग = 1.66 × 10-6 mol L-1s-1

अथवा
(अ) कार्बिलेमीन और हॉफमान ब्रोमाइड अभिक्रियाओं पर टिप्पणी लिखिए।
(ब) निम्नलिखित को उनके बढ़ते हुए क्षारकीय प्रबलता के क्रम में लिखिए। (2 + 1 = 3)
C2H5NH2, C6H5NH2, NH3, C6H5CH2NH2 तथा (C2H5)2 NH
उत्तर:
RBSE 12th Chemistry Model Paper Set 4 with Answers in Hindi 21
(ब) (A) चूँकि यौगिक ‘C’ (अणुसूत्र C6H7N) यौगिक ‘B’ की Br2, तथा KOH से अभिक्रिया होने पर बनता है, इसलिए यौगिक ‘B’ एक ऐमाइड तथा . यौगिक ‘C’ ऐमीन होना चाहिए। अणुसूत्र C6H7N से केवल एक ऐमीन C6H5NH6, (ऐनिलीन) प्राप्त हो सकती है। अतः यौगिक ‘C’ . ऐनिलीन (IUPAC नाम) है।
(B) चूँकि ‘C’ ऐनिलीन है, इसलिए वह ऐमाइड जिससे यह बनता है, बेन्जेमाइड होना चाहिए। अतः यौगिक ‘B’ बेन्जेमाइड (IUPAC नाम) है।
RBSE 12th Chemistry Model Paper Set 4 with Answers in Hindi 22

(C) चूँकि यौगिक ‘B’ ऐरोमैटिक यौगिक ‘A’ को जलीय अमोनिया के साथ गर्म करने पर प्राप्त होता है इसलिये यौगिक ‘A’ बेन्जोइक अम्ल (IUPAC नाम) होना चाहिए।

Question 4.
Read the passage given below and answer the questions that follow:

Vitamin C is an essential ingredient for human beings. It is required for the synthesis of intercellular cement “collagen”, which is responsible for keeping various cells of the human body together. As an oxidant, it acts like a cop in the body, apprehending the rowdy molecules called free radicals that are naturally formed during various chemical reactions in the body and have the potential to damage. Vitamin C is also required for dentine formation in the teeth and it also aids in the absorption of iron from the body.

RBSE 12th English Compulsory Model Paper Set 7 with Answers

Rats have the capacity to synthesise vitamin C With their body whereas human beings are required tQ provide it through diet. The richest source of vitamin C is amla. The other sources are lemon, orange, papaya, pineapple, cabbage, cauliflower, green peas and tomato. While cooking above 70 degree centigrade, Vitamin C gets destroyed.

Scurvy is a disease caused by the deficiency of this vitamin. Due to its deficiency, gums are swollen or bleeding, bones are weak and readily fractured, delayed wound healing and poor teeth formation in children result. A balanced diet with vitamin C is the requirement to avoid scurvy. For pregnant or lactating mothers vitamin C is the remedy. Each adult is required to consume 75 mg per day; an infant 30 mg per day; a pregnant woman 100 mg per day; a lactating mother 150 mg per day. Doctors use vitamin C for the treatment of infections, healing of ulcers, bums and trauma, quick healing of fractures, etc. However, taking vitamin C tablets on a long-term basis is not without side-effects, like the reformation of oxalates, kidney stones, diarrhoea, abnormal heart rhythm, damage to the outer layer of teeth and rebound scurvy if tablets are stopped abruptly.

Amla with honey is a supertonic, particularly when treated with solar rays since honey is an ingredient that provides instant energy without consuming insulin for its absorption in the body. A newly born child in India is first provided with honey to purify his/her internal system since it acts as antibiotic and also without side-effects. Most of us are not aware that during World War II a lot of food material was sent to the British army fighting for and on behalf of the British Government in different parts of the world. In this food material amla was one of the main ingredients to protect fighting forces from scum disease since during day-time they had to live in bunkers and during night-time they had to fight. Therefore, they were generally deprived of sunlight which is a major source of vitamins for human body.

Therefore, vitamin C in the form of amla is the best for human health.

Question 5.
Read the passage given below and answer the questions that follow:

Rabindranath Thakur was born in Calcutta on May 7, 1861. His father Devendranath Thakur, was a well-known social and religious leader and was called Maharshi Devendranath. Though a religious leader, Devendranath was very broad-minded and he encouraged his son to think independently.

In school, Rabindranath found the teaching too elementary. It did not take his teacher long to recognise his intelligence. He was given ‘Macbeth’ to translate and to everyone’s surprise Rabindranath made a very good translation into Bengali. However, his limitless curiosity to know more and newer things could not be satisfied in school. It was, therefore, decided to withdraw him from there. For four years, from the age of thirteen to seventeen, he studied a wide variety of subjects at home. About the same time he was drawn to Nature and Arts. For hours, he would go swimming in the Ganga and watch the changing moods of that mighty river. He also started composing verses and learning music.

From 1881 onwards his talent as a writer expressed itself in the form of countless compositions in poetry, drama, prose, music, fiction, philosophy and painting. He wrote nearly 50 plays, 100 books of verse and 40 volumes of fiction and philosophical writings. Rabindranath was also a great educationist. In 1901, he founded a school at Shantiniketan near Bolpur in Bengal. Situated in the midst of natural surroundings, it soon started attracting students from all over the country and even from outside India. In 1922 it was changed into an international university called Vishva-Bharati, the name it continues to have to this day. The work which brought him universal recognition was a collection of poems named ‘Gitanjali’. Originally written in Bengali, it was translated into English by Rabindranath himself. This won him in 1913 the Nobel Prize in Literature and made him internationally famous.

RBSE 12th English Compulsory Model Paper Set 7 with Answers

Rabindranath was a great nationalist and patriot. He felt so bitter about the Jallianwala Bagh tragedy in 1919 that as a protest, he gave up Knighthood which the British had awarded him earlier. But his nationalism was not based on any narrow loyalties. It was a part of his wider vision of internationalism and world brotherhood. He died on August 07, 1941, four years before the founding of the U.N.O. and six years before the coming of Indian independence. Though he is no more, his message of universal peace and love amongmankind will continue to inspire many generations to come.

OR
Why does the writer feel elated when she thinks about Mukesh? (Lost Spring)
Answer:
In my opinion, the title of the lesson ‘The Last Lesson’ is quite appropriate. The lesson presents a vivid description of M. Hamel’s last lesson in the class on the last day. There came an order from Berlin banning the teaching of French. According to the order only German was to be taught in the schools of Alsace and Lorraine. Addressing the students he said, “My children, this is my last lesson in French”. On his last day he taught so well that every student was attentive to him.
OR
Mukesh belongs to a family of bangle makers. The author thinks that there are two distinct worlds- the world of the poor and the world of the rich. A poor child falls in the net of the rich before he is aware of it. Doing anything Other than what his generations have been doing needs courage. Mukesh dreams of becoming a motor mechanic. He seems courageous enough to break away from the cycle of work his family has been doing for generations. When the author senses a flash of courage in Mukesh, she gets elated.

“The story ’ The Rattrap’ is a mixture of entertainment and philosophy”. Explain. (The Rattrap)
Answer:
When Douglas was thrown into the pool, he was drowning down in a 9 feet deep pool and these 9 feet seemed 90 to him. He was under the vicious grip of terror but still conscious to plan a strategy of bouncing back as and when he would strike against the bottom. He did the same, but failed. He was all soaked and choked. Once again he was sinking down, this time in a subconscious state. His head still urged him to spring upwards like a cork but the second jump was no better. Then he started another journey down but this one was quite peaceful and relaxed.
OR
The story ‘The Rattrap’ is entertaining and philosophical as well. The ironmaster mistakes the peddler for his old friend. This episode amuses the readers a lot. But the comparison between a rattrap and this world conveys a deep philosophical message. This world provides us with the stuff that allures us. Just as a bait is used to trap a rat, worldly enjoyments are used to trap human beings. The story so beautifully highlights the human dilemma that one wonders in awe whether one should accept the allurements or reject them.

Question 21.
How was Charley’s reaching the third level a waking-dream wish fulfilment? (The Third Level) (3)

So, Charley felt very good about that. He thought of living a simple and romantic life as the people did in the past. The thought was quite soothing to him.
OR
In the story ‘The Tiger King’, we see innocent tigers being killed at the whim of a king. Just to prove the prediction of the astrologers wrong, the proud king does so. The author seems to comment that a killer of innocent animals is never spared by nature. It seems to be a lesson for those who are cruel to innocent animals and treat them at their will.

Question 22.
What is the message of the story ‘The Enemy’? (The Enemy) (3)
OR
How did Mr Lamb’s meeting with Derry become a turning point in Derry’s life? (On the Face of R)
Answer:
This story gives the message of human love and brotherhood. It teaches us to rise above narrow feelings of nationality and consider the whole world as our family. A Japanese doctor saves the life of an American soldier at the time when Japan and America are at war. His patriotism demands him to hand over the soldier to the police but his goodness as a doctor prompts him to heal his wound. Thus we learn to develop human feelings in us.
OR

Through the esteemed columns of your newspaper I wish to attract the attention of the authorities concerned of the Jhalawar Municipal Board to the poor lighting arrangement in the city.

Being an old city, Jhalawar has many narrow streets. Unfortunately, the lighting arrangement too is very old and poor. So, most of the streets remain dark due to lack of proper street lights.

Will the Municipal authorities do something to solve the problem and earn a good name for the department ?

Question 4.
Read the passage given below and answer the questions that follow-

There are no rules to tell us how we ought to behave or ought not to behave in all matters. Rut in some matters, there are rules that all have to obey, ‘lake, for example the rules of the road. The purpose of these rules is to make the road safe for everybody. The roads in our cities and towns are getting more and more busy with traffic these days. All kinds of vehicles, (some slow’ some fast), fill the roads during the great er part of the day. If people disobey traffic rules, accidents will happen sooner or later. There are rules for pedestrians as well as for vehicles, and every user of the road ought to know the rules.

Here is an important rule for pedestrians they ought to keep to the footpath and leave the middle of the road for vehicles. Where there is no footpath, pedestrians must keep close to the edge of the road. If they do not obey this rule, they will cause danger to themselves as well as to others. A driver may turn his vehicle suddenly to avoid a pedestrian and, in doing so, may knock down someone else. I le may even lose control of his vehicle and drive over the footpath and knock down several people.

All vehicles should keep to the left and leave the right half of the road free for those coming from the opposite direction this is the traffic rule in all parts of India. In some countries in the west, however, vehicles have to keep to the right and not to the left. It does not matter whether it is right or left but, everyone should obey the rule. Cyclists should always keep to the edge of the road and not get in the way of other vehicles or pedestrians We often see two or more cyclists riding together side by side right in the middle of the road. Traffic rules do not allow this. Where the road is busy, this will interfere with the flow’ of traffic and cause accidents. The rule about overtaking is an equally important rule. One vehicle should overtake another vehicle only on the right, because otherwise it may get in the way of the vehicle which is trying to keep to the left. There are rules about right of way where roads cross each other. There is usually a roundabout at these places.The vehicle coming from the right has right of way over the one coming from the left. If every driver follows this rule, traffic at roundabouts will flow quite smoothly and accidents can be avoided.

RBSE 12th English Compulsory Model Paper Set 6 with Answers

Drivers of vehicles should never fail to give the right signals, because otherwise there is great danger of accidents happening. There are signals for turning right or left, for slowing down and for stopping, and for letting another vehicle overtake yours. Cyclists are often careless about giving signals, thinking that these are important only for motorists. But all road users, cyclists as well as motorists, ought to have the right signals so that others on the road maybe warned. Pedestrians too should have a knowledge of these signals so that they may be able to tell which way the vehicles on the road are going to pass. Above all, everyone using the public road ought to obey the policeman on traffic duty. This is the most important rule of all.

(i) Which rules should we obey? (2)
(ii) What will happen if the drivers of vehicles do not give proper signals? (2)
(iii) What is the purpose of traffic rules? (2)
(iv) What is the traffic rule for pedestrians? (2)

(iii) The purpose of the traffic rules is to make the road safe for everybody
(iv) Pedestrians ought to keep to the footpath or close to the edge of the road.
(v) knock down, greater

Question 5.
Read the passage given below and answer the questions that follow-

The test of a great book is whether we want to read it only once or more than once. A really great book is one which we want to read the second time even more than we wanted to read it the first time; and every additional time that we read it we find new ‘meanings and new beauties in it. A book that a person of education and good taste does not care to read more than once is very probably not worth much. But we cannot consider the judgment of a single individual infallible. The opinion that makes a book great must be the opinion of many. For even the greatest critics are apt to have certain dullness.

Carlyle, for example, could not endure Browning; Byron could not endure some of the greatest of English poets. A man must be many-sided to utter a trustworthy estimate of many books. We may doubt the judgment of the single critic at times. But there is no doubt possible in regard to the judgment of generations. Even if we cannot at once perceive anything good in a book which has been admired and praised for hundreds of years, we may be sure that by trying, by studying it carefully, we shall at least be able to feel the reason of this admiration and praise. The best of all libraries for a poor man would be a library entirely composed of such great works only, books which have passed the test of time.

RBSE 12th English Compulsory Model Paper Set 6 with Answers

This then would be the most important guide for us in the choice of readings. We should read only the books we want to read more than once, nor should we buy any others, unless we have some special reason for so investing money. The second fact demanding attention is the general character of the value that lies hidden within all such great books. They never become old their youth is immortal. A great book is not apt to be comprehended by a young person at the first reading except in a superficial way. Only the surface, the narrative, is absorbed and enjoyed. No young man can possibly see at first Reading the qualities of a great book. Remember that it has taken humanity in many pases hundreds of years to find out all that there is in such a book. But according to a man’s experience of life, the text will unfold new meanings to him.

The book that delighted us at eighteen, if it be a good book, will delight us much more at twenty-five and it will prove like a new book to us at thirty years of age. At forty we shall re-read it, wondering why we never saw how beautiful it was before. At fifty or sixty years of age the same facts will repeat themselves. A great book grows exactly in proportion to the growth of the reader’s mind.

(i) What is the quality of a great book? (1)
(ii) In which case is a judgment about a book beyond doubt? (1)
(iii) What kind of understanding of a great book is a young person likely to have at the first reading of that book? (1)
(iv) Whose work did Carlyle find difficult to appreciate? (1)
(v) What would a poor man’s library contain? (1)
Answer:
(i) The quality of a great book is that we want to read it again and again.
(ii) There is no doubt possible in regard to the judgment of generations.
(iii) A great book is not apt to be comprehended by a young person at the first reading except in a superficial way.
(iv) Carlyle found it difficult to appreciate the work of Browning.

Answer:
Both these women are from marginalised communities. One girl in The Cutting of My Long Hair’ is an American Indian. The native Americans thrust their culture on her. The other girl in ‘We Too Are Human Beings’ belongs to a so-called Indian lower caste. She sees an elderly person of her caste bearing insult.

Both the girls fight against the inhuman treatment in their own way. The first one kicks and scratches to avoid her hair being shingled. The other one studies hard and earns a reputation for herself.

One day, he is playing with his son with a wooden tiger which has sharp slivers of wood. One such piece pierces his hand. The wound takes his life. Thus, it is a fine example of dramatic irony.
OR

ऑक्साइड में ऑक्सीजन की धातुओं के साथ बहुआबन्ध बनाने की क्षमता, फ्लुओराइड में उपस्थित फ्लुओरीन की तुलना में अधिक होती है। इस कारण Mn उच्च ऑक्सीकरण अवस्था में ऑक्साइड Mn2O7, बनाता है, फ्लोराइड MnF7, नहीं।

(vi) ईथर को कभी भी शुष्कता तक गर्म नहीं करते, क्यों ? (1)
उत्तर:
ईथर के ऑक्सीकरण से बने परॉक्साइड विस्फोटक होते हैं जो कि शुष्कता तक गर्म करने पर विस्फोट कर सकते हैं। अतः ईथर को कभी भी शुष्कता तक गर्म नहीं किया जाता है।

(vii) ऐरोमैटिक ऐमीनों में इलेक्ट्रॉनस्नेही प्रतिस्थापन, बेन्जीन की तुलना में शीघ्रता से क्यों होता है। (1)
उत्तर:
अनुनाद के कारण ऐनिलीन के N-परमाणु पर इलेक्ट्रॉन बेन्जीन वलय पर विस्थानीकृत (delocalised) हो जाते हैं जिसके परिणामस्वरूप बेन्जीन वलय पर इलेक्ट्रॉन घनत्व बढ़ जाता है। दूसरे शब्दों में, ऐनिलीन सक्रिय हो जाती है अतः ऐनिलीन में इलेक्ट्रॉनस्नेही प्रतिस्थापन शीघ्रता से होता है।

(viii) क्या होता है जब एथिलेमीन की क्रिया एथिल मैग्नीशियम ब्रोमाइड से कराते हैं?
उत्तर:
एथेन बनती है।

प्रश्न 5.
यदि NaCl को SrCl2, के 10-3 मोल % से डोपित किया जाये तो धनायनों की रिक्तियों का सान्द्रण क्या होगा? (1½)
उत्तर:
NaCl को SrCl2 के 10-3 मोल % से डोपित करते हैं।
अर्थात् 100 भाग NaC1 में = 10-3 मोल SrCl2
1 भाग NaCl में = \(\frac{10^{-3}}{100}\) मोल SrCl2
= 10-5 मोल SrCl2
= 6.022 × 1023 × 10-5 SrCl2,
= 6.022 × 12+ आयन एक रिक्ति उत्पन्न करता है, अतः .
रिक्तियाँ = 6.022 × 1018

प्रश्न 6.
स्थिरक्वाथी विलयन क्या हैं ? ये कितने प्रकार के होते हैं? (1½)
उत्तर:
(i) ऐसे द्विघटकीय मिश्रण, जिनका द्रव व वाष्प प्रावस्था में संघटन समान होता है तथा जो एक स्थिर ताप पर उबलते हैं एवं जिनके घटकों को प्रभाजी आसवन द्वारा अलग नहीं किया जा सकता है। स्थिरक्वाथी विलयन कहलाते हैं। ये दो प्रकार के होते हैं-

(ii) न्यूनतम क्वथनांकी स्थिरक्वाथी- जो विलयन एक निश्चित संगठन पर रॉउल्ट नियम से अत्यधिक धनात्मक विचलन प्रदर्शित करते हैं, न्यूनतम स्थिरक्वाथी विलयन कहलाते हैं। उदाहरणएथेनॉल एवं जल।

(iii) अधिकतम क्वथनांकी स्थिरक्वाथी- वे विलयन जो कि रॉउल्ट नियम से बहुत अधिक ऋणात्मक विचलन दर्शाते हैं। एक विशिष्ट संगठन पर अधिकतम क्वथनांकी स्थिरक्वाथी विलयन कहलाते हैं। उदाहरण- नाइट्रिक अम्ल व जल।

प्रश्न 7.
25°C पर गन्ने की शक्कर के विलयन का परासरण दाब 5atm है। विलयन का सान्द्रण mol L-1 में ज्ञात कीजिए, यदि R = 0.821 L atm K-1 mol-1 है। (1½)
उत्तर:
ताप T = 25 + 273
= 298 K
विलेय का अणुभार WB = C12 H22 O11
= 12 × 12 + 1 × 22 + 16 × 11
= 342 g/mol
परासरण दाब π = 5 atm
गैस नियतांक R = 0.0821 L atm K-1 mol-1
C = π RT
C = \(\frac{\pi}{\mathrm{RT}}\) = \(\frac{5}{0.0821 \times 298}\)
= 0.20 mol L-1

प्रश्न 8.
(अ) आरेख में चिन्हित (क) एवं (ख) किसे दर्शाते हैं? नाम लिखिये।
(ब) आरेख में चिन्हित केवल (क) की परिभाषा दीजिये। (¾ + ¾ = 1½)
RBSE 12th Chemistry Model Paper Set 2 with Answers in Hindi 3
उत्तर:
(अ) आरेख में (क) अभिकारकों की सक्रियण ऊर्जा है तथा (ख) ऊर्जा परिवर्तन (ΔH) है जो अभिकारकों एवं उत्पादों की ऊर्जा में अंतर को बताता है।
(ब) सक्रियण ऊर्जा-अभिकारकों से सक्रियत संकुल (मध्यवर्ती) के निर्माण के लिये आवश्यक ऊर्जा सक्रियण ऊर्जा (EA) कहलाती है। फिर यह संकुल (मध्यवर्ती) उत्पाद में परिवर्तित होता है।

प्रश्न 9.
SO2,Cl2, को अपनी प्रारम्भिक मात्रा से आधी मात्रा में वियोजित होने में 60 मिनट का समय लगता है। यदि अभिक्रिया प्रथम कोटि की हो तो वेग स्थिरांक की गणना कीजिए। (1½)
उत्तर:
t1/2 = 60 मिनट
मिनट प्रथम कोटि के लिए,
k = \(\frac{0.693}{t_{1 / 2}}=\frac{0.693}{60}\)
या k = 0.01155 min-1
या k = \(\frac{1 \cdot 155}{60}\) × 10-2 s-1
∴ k = 1.925 × 10-4 s-1
अतः वेग स्थिरांक = 1.925 × 10-4 s-1

प्रश्न 10.
निम्नलिखित गैसीय आयनों में अयुग्मित इलेक्ट्रॉनों की गणना कीजिए
Mn3+, Cr3+, V3+ तथा Ti3+
इनमें से कौन-सा जलीय विलयन में अति स्थायी है? (1½)
उत्तर:
Mn3+ के d-उपकोश में चार इलेक्ट्रॉन (3d4) हैं; अतः इसमें चार अयुग्मित इलेक्ट्रॉन होते हैं।
Cr3+ के d-उपकोश में तीन इलेक्ट्रॉन (3d3) हैं, अतः इसमें तीन अयुग्मित इलेक्ट्रॉन होते हैं।
v3+ के d-उपकोश में दो इलेक्ट्रॉन (3d2) हैं, अतः इसमें दो अयुग्मित इलेक्ट्रॉन होते हैं।
Ti3+ के d-उपकोश में एक इलेक्ट्रॉन (3d1) है, अतः इसमें एक अयुग्मित इलेक्ट्रॉन होता है।
इनमें से Cr3+ जलीय विलयन में अति स्थायी है; क्योंकि इसमें अर्द्धपूरित t2g स्तर अर्थात् (t2hg2)3 होता है।

प्रश्न 13.
निम्नलिखित को समझाइए
(अ) ऐल्कोहॉल का अणुभार बढ़ने पर जल में इनकी विलेयता घटती है।
(ब) पावर ऐल्कोहॉल क्या है? इसका उपयोग क्या है?
(स) फीनॉल अम्लीय होते हैं। क्यों ? (½ + ½ + ½ = 1½)
उत्तर:
(अ) क्योंकि ऐल्किल समूह जलविरोधी होते हैं तथा जल में अविलेय हैं। निम्न ऐल्कोहॉल में ऐल्किल समूह छोटा होता है तथा ऐल्कोहॉल का – OH समूह अणु को जल में विलेय बनाने में प्रभावी रहता है। जैसे-जैसे ऐल्किल समूह का आकार बढ़ता है उच्च अणुभार के ऐल्कोहॉलों में ऐल्किल समूह की जल विरोधी प्रकृति -OH समूह की जल स्नेही प्रकृति पर प्रभावी होती जाती है इसलिए विलेयता घटती है।
(ब) परिशोधित स्पिरिट बेंजीन की उपस्थिति में पेट्रोल में मिश्रित हो जाती है। पेट्रोल + औद्योगिक ऐल्कोहॉल और बैंजीन का मिश्रण मोटर ईंधन के रूप में प्रयुक्त किया जाता है। यह मिश्रण पावर ऐल्कोहॉल कहलाता है।
(स) फीनॉल को जल में घोलने पर यह H+ आयन तथा फीनॉक्साइड आयन देता है। जो अनुनाद के कारण स्थायी होता है। इसलिए फीनॉल अम्लीय गुण प्रदर्शित करता है।

प्रश्न 15.
(अ) ऐल्कोहॉल की तुलना में फीनॉल अधिक अम्लीय क्यों होता है? समझाइए।
(ब) निम्नलिखित ऐल्कोहॉलों की एस्टरीकरण अभिक्रिया के प्रति उनकी बढ़ती अभिक्रियाशीलता के क्रम में व्यवस्थित कीजिए (¾ + ¾ = 1½)
CH3 -CH2-OH, (CH3)2 CH-OH, (CH3)3C-OH
उत्तर:
(अ) फीनॉल में अनुनाद पाया जाता है। इस कारण फीनॉल अणु में आवेश वितरण से – OH समूह की ऑक्सीजन धनावेशित हो जाती है और इसका अम्लीय व्यवहार बढ़ जाता है। जबकि मेथैनॉल में अनुनादी संरचना नहीं पायी जाती है। इस कारण यह फीनॉल से कम अम्लीय होता है।

(ब) (CH3)3 COH < (CH3)2 < CH-OH, CH3CH2OH

दीर्घ उत्तरीय प्रश्न

प्रश्न 16.
अभिक्रिया के वेग पर उत्प्रेरक की उपस्थिति का क्या प्रभाव पड़ता है? ग्राफ देकर स्पष्ट कीजिए। (3)
अथवा
(अ) निम्नलिखित अभिक्रियाओं के वेग व्यंजकों से इनकी अभिक्रिया की कोटि व वेग स्थिरांकों की इकाइयाँ ज्ञात कीजिए-
(i) 3NO(g) → N2O(g) + NO2(g), वेग = k[NO]2
(ii) H2O2(aq) + 3I– (aq) + 2H– → 2H2O(l) + I3– वेग = k[H2O2] [I–]
(ब) एक प्रथम कोटि की अभिक्रिया का वेग स्थिरांक 1.15 × 10-3S-1 है। इस अभिक्रिया को अभिकारक की 5 ग्राम मात्रा को घटकर 3 ग्राम होने में कितना समय लगेगा? (2 + 1 = 3)
उत्तर:
उत्प्रेरक का प्रभाव (Effect of Catalyst)-उत्प्रेरक वह पदार्थ है जो स्वयं स्थायी रूप से परिवर्तित हुए बिना अभिक्रिया के वेग को परिवर्तित कर देता है। उदाहरणार्थ- MnO2 निम्नांकित अभिक्रिया को उत्प्रेरित कर वेग में महत्त्वपूर्ण वृद्धि करता है-
2KClO3 → 2KCl + 3O2,
RBSE 12th Chemistry Model Paper Set 2 with Answers in Hindi 7

उत्प्रेरक की क्रिया को मध्यवर्ती संकुल सिद्धान्त से समझा जा सकता है। इस सिद्धान्त के अनुसार उत्प्रेरक रासायनिक अभिक्रिया में भाग लेकर अभिकारकों के साथ अस्थायी बन्ध बनाती है जो कि मध्यवर्ती संकुल में परिणत होता है। इसका अस्तित्व क्षणिक होता है तथा यह वियोजित होकर उत्पाद एवं उत्प्रेरक देता है। यह विश्वास किया जाता है कि उत्प्रेरक एक वैकल्पिक पथ अथवा क्रियाविधि से अभिकारकों के उत्पादों के मध्य सक्रियण ऊर्जा कम करके एवं इस प्रकार ऊर्जा अवरोध में कमी करके अभिक्रिया सम्पन्न करता है जैसा कि चित्र में दर्शाया गया है। आरेनियस समीकरण से यह स्पष्ट है कि सक्रियण ऊर्जा का मान जितना कम होगा अभिक्रिया को वेग उतना अधिक होगा।

उत्प्रेरक की लघु मात्रा अभिकारकों की दीर्घ मात्रा को उत्प्रेरित कर सकती है। उत्प्रेरक अभिक्रिया की गिब्ज ऊर्जा, ΔG में बदलाव नहीं करता। यह स्वत:प्रवर्तित (spontaneous) अभिक्रियाओं को उत्प्रेरित करता है, परन्तु स्वत:अप्रवर्तित अभिक्रिया को उत्प्रेरित नहीं करता। यह भी पाया गया है कि उत्प्रेरक किसी अभिक्रिया के साम्य स्थिरांक में परिवर्तन नहीं करता, किन्तु यह साम्य को शीघ्र स्थापित करने में सहायता करता है। यह अग्र एवं प्रतीत दोनों अभिक्रियाओं को समान रूप से उत्प्रेरित करता है जिससे साम्यावस्था अपरिवर्तित रहती है, परन्तु शीघ्र स्थापित हो जाती हैं।

(ii) आयोडोबेन्जीन (1 + 2 = 3)
अथवा
(अ) निम्न यौगिकों के IUPAC नाम दीजिए
(i) CICH2C = CCH2Br,
(ii) CH3C(p-CIC6H4)2CH(Br)CH3
(ब) ग्रीन्यार अभिकर्मक का विरचन निर्जल अवस्थाओं में करना चाहिए। क्यों? (2 + 1 = 3)
उत्तर:
(अ) क्लोरोबेन्जीन की निम्न अनुनादी संरचनायें होती हैं
RBSE 12th Chemistry Model Paper Set 2 with Answers in Hindi 8
अनुनाद के कारण, C-Cl के मध्य अधिक द्विबन्ध गुण आ जाने के कारण, C-Cl की बन्ध ऊर्जा में वृद्धि हो जाती है। अत: C-Cl बन्ध किसी नाभिक स्नेही प्रतिस्थापी समूह के द्वारा आसानी से प्रतिस्थापित नहीं हो पाता अतः कम क्रियाशील है।

RBSE 12th Chemistry Model Paper Set 2 with Answers in Hindi 11
(ब) एनीलीन की अनुनादी संरचनाएँ लिखिए। (2 + 1 = 3)
उत्तर:
(अ) मेथिलेमीन एनिलीन की तुलना में प्रबल क्षारीय होती है। CH3 समूह के + I प्रभाव के कारण N पर इलेक्ट्रॉन घनत्व बढ़ता है, जिससे क्षारीय प्रवृत्ति बढ़ती है जबकि ऐनिलीन अनुनाद के कारण स्थायी हो जाता है। अतः इलेक्ट्रॉन त्यागने की प्रवृत्ति घटती है एवं क्षारकता घटती है।

(ब) उपर्युक्त दी गई जानकारी यह बताती है कि यौगिक ‘A’ एक प्रतिस्थापित ऐमाइड होना चाहिए
RBSE 12th Chemistry Model Paper Set 2 with Answers in Hindi 12
यौगिक (B) HNO2 से क्रिया करके एक पीला तैलीय द्रव बनाता है, अतः यह एक द्वितीयक ऐमीन है।

while adversely affecting the patient’s health on the other.

This situation is termed bv medical experts as microbial resistance’. Various researches and studies carried out in this context also lead to the conclusion that medicines are becoming poisonous.

The chief cause of this situation is the unrestrained use of antibiotics. Studies have revealed tha: sometimes strong antibiotics are taken even for treating simple problems.

‘व्यक्ति को उसकी संगत से जाना जाता है।’ इस कथन का अभिप्राय है कि संगत ही किसी व्यक्ति के चरित्र और व्यक्तित्व को प्रभावित करती है। आमतौर पर यह संगत मित्रों और पुस्तकों की होती है। यदि मित्र अच्छे हैं तो उनका प्रभाव भी अच्छा होता है। पुस्तकों के बारे में भी यही सत्य है। अच्छी पुस्तकें मनुष्य को अच्छा बनने में सहायक होती है जबकि बुरी पुस्तकें उसको बिगाड़ देती है। इसलिये हमेशा अच्छे मित्रों के साथ रहना और अच्छी पुस्तकें पढ़ना ही बुद्धिमत्तापूर्ण होता है। उनकी संख्या महत्त्वपूर्ण नहीं होती। जैसे थोड़े से अच्छे मित्र मित्रता का सुख भोगने के लिये पर्याप्त होते हैं वैसे ही थोड़ी सी अच्छी पुस्तकें व्यक्ति में अच्छे जीवन के अच्छे गुणों को सिखाने के लिये पर्याप्त होती हैं।
