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 understand the concepts and reactions associated with each chemical term given in List I and find the corresponding match in List II:

1. Benzene sulphonyl chloride: This compound is used as Hinsberg's reagent, which is employed to differentiate between primary, secondary, and tertiary amines. The correct match is III: Hinsberg reagent.
2. Hoffmann bromamide reaction: This is a reaction where an amide is converted to an amine with one fewer carbon atom, usually releasing isocyanates. It is known for the formation of nitriles or isocyanates. The correct match is IV: Known reaction of Isocyamates.
3. Carbylamine reaction: This is a reaction to test for primary amines, wherein the primary amine reacts with chloroform and an alkali to produce isocyanide, which has a foul odor. The correct match is I: Test for primary amines.
4. Hoffmann orientation: This refers to the Hoffmann elimination, which results in the anti-Saytzeff elimination product, typically favoring the less substituted alkene. The correct match is II: Anti Saytzeff.

Therefore, the correct matching of List I with List II is: A-III, B-IV, C-I, D-II.
