Vedclass · Answer

(C) $1$. The reaction is the Stephen reduction of a nitrile. Isopropyl cyanide is $(CH_3)_2CH-CN$.$2$. In the first step, the nitrile is reduced by $SnCl_2/HCl$ to form an imine intermediate $(A)$, which is $(CH_3)_2CH-CH=NH$.$3$. In the second step, the acid hydrolysis of the imine $(A)$ yields the corresponding aldehyde $(B)$.$4$. The reaction is: $(CH_3)_2CH-CN \xrightarrow{SnCl_2, HCl} (CH_3)_2CH-CH=NH \xrightarrow{H_3O^+} (CH_3)_2CH-CHO + NH_4Cl$.$5$. The product '$B$' is $(CH_3)_2CH-CHO$, which is $2-	ext{Methylpropanal}$.
