Given below are two statements, one is labelled as Assertion (A) and other is labelled as Reason (R). Assertion (A): Gabriel phthalimide synthesis cannot be used to prepare aromatic primary amines. Reason (R): Aryl halides do not undergo nucleophilic substitution reaction. In the light of the above statements, choose the correct answer from the options given below:

1. Both (A) and (R) true but (R) is not the correct explanation of (A).
2. (A) is false but (R) is true.
3. Both (A) and (R) true and (R) is correct explanation of (A).
4. (A) is true but (R) is false.

Correct answer: Both (A) and (R) true and (R) is correct explanation of (A).

Solution

Gabriel phthalimide synthesis fails for aromatic primary amines precisely because aryl halides do not undergo the nucleophilic substitution needed to react with potassium phthalimide. So both statements are true and the Reason is the correct explanation of the Assertion.
