Vedclass · Answer

(C) The reaction sequence is as follows:$1$. Phenol reacts with $Br_2$ in $CS_2$ (a non-polar solvent) at low temperature. This electrophilic aromatic substitution reaction favors the formation of the para-isomer due to steric hindrance at the ortho-position. Thus,$X$ is $4$-bromophenol.$2$. In the second step,$4$-bromophenol reacts with $NaOH$ to form sodium $4$-bromophenoxide,which then undergoes a nucleophilic substitution reaction $(S_N2)$ with methyl iodide $(MeI)$ to form $1$-bromo-$4$-methoxybenzene $(Y)$. This is an example of Williamson's ether synthesis.Therefore,the correct option is $C$.

In the above sequence of reactions,the major products $X$ and $Y$ are
