Explanation Question:

Question is asking about the total number of amine which can be synthesized by Gabriel synthesis.

Concept:

This question is based on Gabriel phthalimide synthesis.

Solution:

Gabriel phthalimide synthesis is used to prepare 1° aliphatic/alicyclic amine in common. Hence amine which can synthesised by Gabriel phthalimide synthesis method is :

(A) $Me_{2} CH - CH_{2} - NH_{2}$

(B) $CH_{3} CH_{2} NH_{2}$

(C) $Ph - CH_{2} - NH_{2}$

Aromatic primary amine cannot be prepared be then method because anyl halide dont undergo nucleophilic substitution with the anion formed by phthalimide.
