Chemistry - AMINES Question with Solution | TestHub

When cyano benzene reacts with hydrochloric acid and water to form benzoic acid which in turn reacts with sodium borohydride to form benzyl alcohol.

Thus benzy lamine is not formed in option (b). Thus using $\mathrm{HCl}/{\mathrm{H}}_2\mathrm{O}$ and ${\mathrm{NaBH}}_4$ is not a correct method of the preparation of benzyl amine from cyano benzene.
