Vedclass · Answer

(D) Benzylamine $(C_6H_5CH_2NH_2)$ is a primary aliphatic amine. When it reacts with nitrous acid $(HNO_2)$,which is generated in situ by the reaction of $NaNO_2$ and $HCl$ at low temperatures $(273-278 \ K)$,it forms an unstable diazonium salt. This diazonium salt immediately undergoes hydrolysis to form benzyl alcohol $(C_6H_5CH_2OH)$ and nitrogen gas $(N_2)$. The reaction is: $C_6H_5CH_2NH_2 + HNO_2 \rightarrow C_6H_5CH_2OH + N_2 + H_2O$. Therefore,the major product is benzyl alcohol.

The major product formed by the reaction of benzylamine with nitrous acid is
