Vedclass · Answer

(A) The reaction is a standard method for the reduction of nitriles to aldehydes known as Stephen's reduction.Step $1$: The nitrile $(CH_3CH_2C \equiv N)$ is reduced by $SnCl_2 / HCl$ to form an imine intermediate $(CH_3CH_2CH = NH)$.Step $2$: The imine intermediate is then hydrolyzed by boiling with water $(H_2O)$ to yield the corresponding aldehyde $(CH_3CH_2CHO)$ and ammonium chloride $(NH_4Cl)$.

$CH_3CH_2C \equiv N \xrightarrow{X} CH_3CH_2CHO$. The compound $X$ is:
