Question

____________ can be prepared exclusively by Gabriel phthalimide synthesis.

विकल्प

• Ethanamine

• Ethylmethylarnine

• Aniline

• N-Phenylbenzenamine

Answer 1

Ethanamine can be prepared exclusively by Gabriel phthalimide synthesis.

Explanation:

Ethanamine (1° aliphatic)

Ethylmetbylamine (2° aliphatic)

N-Phenylbenzenamine (2° aromatic)

Aniline (1° aromatic)

Gabriel phthalimide synthesis is only used to make aliphatic primary amines. Because aryl halides do not undergo nucleophilic substitution with the phthalimide anion, this approach cannot be used to make aromatic primary amines.
