Question

Assertion (A): Aromatic primary amines cannot be prepared by Gabriel phthalimide synthesis.

Reason (R): Aryl halides do not undergo electrophilic substitution with anion formed by phthalimide.

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true but R is not the correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Answer 1

Answer: (C)

Option (3) A is true but R is false

Answer 2

Gabriel phthalimide synthesis works via an SN2 mechanism with alkyl halides, not aryl halides. Aromatic primary amines cannot be prepared by this method because aryl halides do not undergo nucleophilic substitution. The reason given erroneously mentions "electrophilic substitution" instead of the correct "nucleophilic substitution." Hence, while the assertion is correct, the reason is false.
