Vedclass · Answer

(B) $1$. The nitration of chlorobenzene with $conc. HNO_3$ and $conc. H_2SO_4$ yields $1$-chloro-$4$-nitrobenzene as the major product $(X)$ because the $-Cl$ group is ortho/para directing and the para-isomer is sterically favored.$2$. The conversion of $1$-chloro-$4$-nitrobenzene to $4$-nitrophenol involves nucleophilic aromatic substitution.$3$. The reaction requires strong nucleophilic conditions,which are provided by $(i) NaOH$ at $443 \ K$ followed by $(ii) H^+$ (acidification) to convert the phenoxide ion to the phenol.$4$. Thus,$Y$ is $(i) NaOH, 443 \ K, (ii) H^+$ and $Z$ is $4$-nitrophenol.

What are $Y$ and $Z$ respectively in the following reaction sequence?
Chlorobenzene $\xrightarrow[Conc. H_2SO_4]{HNO_3}$ $X$ (major product) $\xrightarrow{Y}$ $Z$
