Explanation Question:

Question is asking about to match reagent reactions given in list-I with their characteristics given in list-II.

Concept:

This question is based on chemical reactions of amines and their preparation methods.

Solution:

(A)

→ Hinsberg reagent Benzene sulphonyl chloride

(B) Hoffmann bromamide reaction: A known reaction of isocyanates.

$R - CON H_{2} + X_{2} + 4 N a O H \to R - N H_{2} + 2 N a X + N a_{2} C O_{3} + 2 H_{2} O$

Intermediate: $R - N = C = O$ (isocyanate)

(C) Carbylamine reaction: test for primary amines.

$R - N H_{2} or A r - N H_{2} + C H C l_{3} + 3 K O H \to RNC or A r - NC + 3 K Cl + 3 H_{2} O$

(D) Hoffmann elimination: Anti-Saytzeff elimination (formation of the less substituted alkene as the major product).
