Vedclass · Answer

(C) The reaction sequence is as follows:$1$. Benzenediazonium chloride reacts with $CuCN/KCN$ to form benzonitrile $(P)$: $C_6H_5N_2^+Cl^- \xrightarrow{CuCN/KCN} C_6H_5CN$ $(P)$.$2$. Benzonitrile $(P)$ is reduced by $LiAlH_4$ to form benzylamine $(Q)$: $C_6H_5CN \xrightarrow{LiAlH_4} C_6H_5CH_2NH_2$ $(Q)$.$3$. Benzylamine $(Q)$ reacts with nitrous acid $(HNO_2)$ to form benzyl alcohol $(R)$: $C_6H_5CH_2NH_2 \xrightarrow{HNO_2} C_6H_5CH_2OH$ $(R)$.Thus,$R$ is benzyl alcohol.

Identify $R$ in the following sequence of reaction:
