The diethyl acetal of $p$-nitrobenzaldehyde and $p$-nitrobenzaldehyde.

Vedclass · Answer

(A) The reaction of $p$-nitrobenzaldehyde with ethanol in the presence of dry $HCl(g)$ is an acetal formation reaction. Aldehydes react with alcohols in the presence of dry $HCl$ to form hemiacetals,which further react with another molecule of alcohol to form acetals. Step $1$: $p$-Nitrobenzaldehyde reacts with $C_2H_5OH$ in the presence of $HCl(g)$ to form the diethyl acetal,$X$,which is $p-NO_2-C_6H_4-CH(OC_2H_5)_2$. Step $2$: The acetal $X$ on hydrolysis with dilute $HCl$ (acidic hydrolysis) regenerates the original aldehyde,$Y$,which is $p-nitrobenzaldehyde$ $(p-NO_2-C_6H_4-CHO)$. Therefore,$X$ is the diethyl acetal and $Y$ is the original aldehyde.
