Solution
Correct Answer:
Aniline
The carbylamine test is given only by primary amines (both aliphatic and aromatic) on heating with chloroform and alcoholic KOH, producing foul-smelling isocyanides. Aniline is a primary aromatic amine, so it gives the test. N,N-Dimethylaniline is tertiary, acetanilide is an amide (not free primary amine), and pyridine is a heteroaromatic base but not a primary amine. Hence only aniline responds positively.
This easy difficulty chemistry question is from the chapter organic compounds containing nitrogen, covering the topic of amines. It appeared in the 2025 exam.
