• A. Aniline
• B. Dimethylaniline
• C. Methylethylamine
• D. Ethylamine

Answer 1

Answer: (D)

Ethylamine

Answer 2

Aliphatic primary amines react with cold nitrous acid to give alcohols with the quantitative evolution of $N_2$ gas.
{\underset{\text{Ethylamine}}{ {C2H5NH2}}$+ HONO ->[273 -278K]$\underset{\text{Ethanol }}{ {C2H5OH}} + N2 + H_2 O }
