Question

Match List I with List II.
 

List-I	List-II
A. Benzene sulphonyl chloride	I. Test for primary amines
B. Hoffmann bromamide reaction	II. Anti Saytzeff
C. Carbylamine reaction	III. Hinsberg reagent
D. Hoffmann orientation	IV. Known reaction of Isocyamates

Choose the correct answer from the options given below:

• A. A-IV, B-III, C-II, D-I
• B. A-IV, B-II, C-I, D-II
• C. A-III, B-IV, C-I, D-II
• D. A-IV, B-III, C-I, D-II

Answer 1

The Correct Option is C

To solve this matching question, we need to associate each item from List-I with the correct option from List-II based on their known chemical reactions and applications. Let's go through each option step by step:

1. Benzene sulphonyl chloride is known as the Hinsberg reagent. It is used for the test of amines, particularly to distinguish between primary, secondary, and tertiary amines. Therefore, A matches with III.
2. The Hoffmann bromamide reaction is a well-known reaction that converts an amide into an amine with the loss of a carbon atom. This reaction also involves the formation of an isocyanate intermediate. Hence, B matches with IV.
3. The Carbylamine reaction is a test for primary amines. It involves the formation of an isocyanate intermediate and produces a foul-smelling compound when primary amines are treated with chloroform and an alcoholic base. So, C matches with I.
4. Hoffmann orientation leads to anti-Saytzeff orientation in elimination reactions. This means that the less substituted alkene (less stable) is formed in preference to the more substituted one. Thus, D matches with II.

Based on the above associations, the correct matching is:

• A - III
• B - IV
• C - I
• D - II

Therefore, the correct answer is:

A-III, B-IV, C-I, D-II
