Assertion (A): Aromatic primary amines cannot be prepared by Gabriel Phthalimide synthesis.Reason (R): Aryl halides do not undergo nucleophilic substitution reaction with the anion formed by phthalimide.
Show Hint
The Gabriel synthesis is a way of synthesizing primary amines from alkyl halides, but does not work effectively with aryl halides due to their poor reactivity in nucleophilic substitution reactions.
Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
Assertion (A) is true, but Reason (R) is false.
Assertion (A) is false, but Reason (R) is true.

The Correct Option isB
Solution and Explanation
Gabriel Phthalimide synthesis is a method used to prepare primary amines, but it does not work with aromatic amines.
Aryl halides do not undergo nucleophilic substitution with the anion formed by phthalimide due to the absence of a good leaving group in aryl halides, but this is not the reason for aromatic primary amines not being prepared.
Step 2:
Thus, both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation for Assertion (A).
