p-Bromophenol and o-Hydroxybenzaldehyde

Vedclass · Answer

(B) $1$. Reaction with $Br_2$ in $CS_2$ at $273 \ K$: This is an electrophilic aromatic substitution reaction. Due to the low polarity of the solvent $CS_2$,the reaction is less polar,leading to the formation of the para-isomer as the major product. Thus,$A$ is $p$-bromophenol.$2$. Reaction with $CHCl_3$ and $NaOH$ followed by $H_3O^+$: This is the Reimer-Tiemann reaction. It introduces a formyl group $(-CHO)$ at the ortho position of the phenol. Thus,$B$ is $o$-hydroxybenzaldehyde (salicylaldehyde).Therefore,the major products are $p$-bromophenol and $o$-hydroxybenzaldehyde.
