How many of the following amines are arylamines?Aniline, Benzylamine…

The correct answer is Option (2) → 3

An amine is an arylamine only when the –NH₂ group is attached directly to the benzene ring. A benzene ring elsewhere in the molecule is not enough.

Arylamines:

• Aniline (–NH₂ on the ring)

• o-Toluidine (–NH₂ on the ring, methyl beside it)

• p-Bromoaniline (–NH₂ on the ring, Br opposite)

Not arylamines:

• Benzylamine, \( \ce{C6H5CH2NH2} \) — –NH₂ is on a CH₂ group, not on the ring.

• 2-Phenylethanamine, \( \ce{C6H5CH2CH2NH2} \) — –NH₂ is two carbons away from the ring.

• Propan-2-amine — no ring at all; an alkylamine.

Arylamines: 3.
