Some MCQ Questions for NEET Exams

1. The reaction of tert butyl bromide with sodium methoxide produces____.

Isobutane, isobutylene, tert-butyl methyl ether, sodium tert butoxide

The answer is isobutylene

Solution:

When the reaction between  tert butyl bromide occurs with sodium methoxide, an elimination takes place. This is the E1cB elimination, wherein the Hoffman alkene is major. Then dehydrohalogenation takes place. Subsequently, rather than an ether, which is typically the case, an alkene is obtained.


2. Which of the following undergoes nucleophilic substitution exclusively by SN1 mechanism?

  1. Benzyl Chloride

  2. Ethyl chloride

  3. Chlorobenzene

  4. Isopropyl chloride

The answer is (a) Benzyl Chloride.


3. The increasing order of nucleophilicity would be?

  1. Cl– < Br– < I–

  2. I– < Cl– < Br–

  3. Br– < Cl– < F–

  4. I– < Br– < Cl–

The Answer is (a) Cl– < Br– < I–


4. Which of the following is most reactive towards SN1 reaction?

  1. C6H5C(CH3)C6H5Br

  2. C8H5CH2Br

  3. C6H5CH(C6H5)Br

  4. C6H5CH(CH3)Br

The answer is (a) C6H5C(CH3)C6H5Br


5. CH3CH2CH2Br + NaCN → CH3CH2CH2CN + NaBr, will be fastest in

  1. ethanol

  2. methanol

  3. N, N-dimethylformamide

  4. Water

The answer is (c) N, N-dimethylformamide.

 

6. A Grignard reagent may be made by reacting magnesium with

  1. Methyl amine

  2. Diethyl ether

  3. Ethyl iodide

  4. Ethyl alcohol

The answer is (c) Ethyl iodide. 


7. C-Cl bond of chlorobenzene in comparison to C-Cl bond in methyl chloride is

  1. Longer and weaker

  2. Shorter and weaker

  3. Shorter and stronger

  4. Longer and stronger

The answer is (c) Longer and stronger.


8. A solution of (+) 2-chloro-2-phenylethane in toluene racemases slowly in the presence of a small amount of SbCl5, due to the formation of

  1. carbanion

  2. carbene

  3. free radical

  4. carbocation

The answer is (d) Carbonation.


9. The decreasing order of boiling points of alkyl halides is

  1. RF > RCl > RBr > RI

  2. RBr > RCl > RCl > RF

  3. RI > RBr > RCl > RF

  4. RCl > RF > RI > RBr

The Answer is RI > RBr > RCl > RF


10. Phosgene is commonly known as

  1. Thionyl chloride

  2. Carbonyl chloride

  3. Carbon dioxide and phosphine

  4. Phosphoryl chloride

The answer is (C) Carbon Dioxide and Phosphine.

FAQs on NEET Important Questions: Haloalkanes and Haloarenes

1. How will these questions help students prepare for NEET?

NEET questions are designed in such a way that they can assess students' required knowledge to allow them to continue learning. While preparing for the exams students use a wide range of learning materials and the most popular learning materials among students is Pre-Chemistry - Chapter-Wise PYP 24 Haloalkanes and Haloarenes Annual Question Papers. This is because PYP (Past Year Papers) allows students to look at the actual papers and their questions asked in last year's exams. Students can solve these papers every day to make it a habit to solve such difficult questions. It also helps them to manage time to try questions.

2. Is it necessary for the students of NEET to prepare important questions from vedantu?

Vedantu never leaves a chance to make education easy for the students. Every concept of Haloalkanes and Haloarenes is discussed in one or the other question. Also, there are solutions available to these questions and those solutions can be very helpful at the preparation level. Solving previous years’ questions will allow students to simplify their learning. This is because students can take the help of solutions whenever they want if they are stuck in some questions. Therefore, students can easily understand problems and their solutions.

3. What were the topics present in last year’s NEET question papers Chemistry - chapter-wise PYP 24 Haloalkanes and Haloarenes?

There are 3 important subjects in the NEET Chemistry Chapter-Wise PYP question papers 24 Haloalkanes and Haloarenes. Those subjects are Biology (Zoology & Botany), Physics, and Chemistry. Each topic is assigned a maximum of 45 questions. That is why each lesson is so important and students should give it equal attention. All the topics are necessary to be covered by the students. Important questions and previous year’s papers will put an effect on the learning level of the students.

4. What is the most common haloalkane?

The most common haloalkane is bromoalkane. There are more than 1600 halogenated organic compounds available today. There are different ways to prepare haloalkanes and haloarenes. We can trace back to the existence of haloalkane in the 15th century. The first haloalkane produced was chloroethane. Later, in the 19th century, refining and synthesis of such compounds were made in order to understand the chemical composition of organisms and the composition of alkanes. This is a very important concept which needs to be learned by the students who are applying for NEET examinations.

5. What do you mean by Haloalkanes and Haloarenes?

Haloalkanes and Haloarenes are very useful living compounds. These are used as solvents, propellants and for many other industrial purposes. Haloalkanes and Haloarenes are the basic themes of CBSE Class 12 biological chemistry. An easy-to-understand topic. Haloalkanes and Haloarenes are derived from the.In haloalkanes, the halogen atom adheres to the sp3 hybridised carbon atom of the alkyl group. In haloarenes, the halogen atom attaches to the sp3 hybridised carbon atom of the alkyl group.
