Vedclass · Answer

(C) $1$. The reaction of aniline with acetic anhydride leads to the formation of $N$-phenylacetamide (acetanilide) as product $X$. This step protects the amino group.$2$. $N$-phenylacetamide undergoes electrophilic aromatic substitution (nitration) with a mixture of concentrated $HNO_3$ and concentrated $H_2SO_4$ at $15^{\circ}C$. The acetamido group $(-NHCOCH_3)$ is ortho/para directing,but due to steric hindrance,the para-isomer is the major product $Y$ ($p$-nitroacetanilide).$3$. Finally,the hydrolysis of $p$-nitroacetanilide with aqueous $NaOH$ removes the acetyl group to yield $p$-nitroaniline as the final product $Z$.

Identify the major products $X$,$Y$,and $Z$ in the following sequence of transformations:
