Assertion: Aromatic 1° amines can be prepared by Gabriel phthalimide synthesis.
Reason: Aryl halides undergo nucleophilic substitution with anion formed by phthalimide.
Explanation:
The Gabriel phthalimide synthesis is a method used to prepare primary amines from alkyl halides. This method is particularly effective for the synthesis of primary aromatic amines.
Assertion is correct:
The Gabriel phthalimide synthesis involves the reaction of an alkyl halide with potassium phthalimide followed by hydrolysis. In this process, the alkyl halide is converted into a phthalimide ester, which is then hydrolyzed to yield the corresponding primary amine.
Reason is correct:
The nucleophilic substitution of aryl halides with the anion formed by phthalimide is an important step in the Gabriel phthalimide synthesis. The phthalimide anion acts as a nucleophile and displaces the halide ion from the aryl halide, resulting in the formation of an aryl phthalimide. This aryl phthalimide can then be hydrolyzed to yield the desired primary aromatic amine.
Reason is a correct explanation of the Assertion:
The reason provided correctly explains how aryl halides undergo nucleophilic substitution with the anion formed by phthalimide. This nucleophilic substitution reaction is an important step in the Gabriel phthalimide synthesis, which ultimately leads to the formation of aromatic primary amines.
Therefore, both the Assertion and Reason are correct, and the Reason is a correct explanation of the Assertion.
Conclusion:
The Gabriel phthalimide synthesis is a reliable method for preparing aromatic primary amines. The nucleophilic substitution of aryl halides with the anion formed by phthalimide is an important step in this synthesis. This reaction allows for the conversion of aryl halides into aryl phthalimides, which can be further hydrolyzed to yield the desired aromatic primary amines.

Therefore, both the Assertion and Reason are correct, and the Reason is a correct explanation of the Assertion.
Conclusion:
The Gabriel phthalimide synthesis is a reliable method for preparing aromatic primary amines. The nucleophilic substitution of aryl halides with the anion formed by phthalimide is an important step in this synthesis. This reaction allows for the conversion of aryl halides into aryl phthalimides, which can be further hydrolyzed to yield the desired aromatic primary amines.

Aromatic primary amines cannot be prepared by Gabriel phthalimide synthesis because it used for the preparation of aliphatic primary amines. It involves nucleophilic substitution (SN2) of alkyl halides by the anion formed by the phthalimide. But aryl halides do not undergo nucleophilic substitution with the anion formed by the phthalimide.
Hence, aromatic primary amines cannot be prepared by Gabriel pthalimide synthesis.
