Vedclass · Answer

(B) The conversion of a nitrile $(R-CN)$ to a primary amine $(R-CH_2-NH_2)$ involves the reduction of the cyano group. $LiAlH_4$ (Lithium aluminium hydride) is a strong reducing agent capable of reducing nitriles to primary amines. The reaction is: $CH_3-CH_2-C \equiv N \xrightarrow{LiAlH_4} CH_3-CH_2-CH_2-NH_2$ Therefore,the correct reagent is $LiAlH_4$.

The most appropriate reagent for the conversion of $C_2H_5CN$ into $CH_3CH_2CH_2NH_2$ is:
