Vedclass · Answer

(A) The reaction proceeds in three main steps:$1$. Reimer-Tiemann reaction: $4$-chlorophenol reacts with $CHCl_3$ and aqueous $NaOH$ to form $5$-chloro$-2$-hydroxybenzaldehyde.$2$. Cross-Cannizzaro reaction: The aldehyde formed reacts with $HCHO$ and concentrated $NaOH$. The aldehyde is reduced to the corresponding alcohol ($5$-chloro$-2$-hydroxybenzyl alcohol), and $HCHO$ is oxidized to sodium formate $(HCOONa)$.$3$. Acidification: Finally, treatment with $H_3O^+$ converts the phenoxide and formate salt into $5$-chloro$-2$-hydroxybenzyl alcohol and formic acid $(HCOOH)$.
