Vedclass · Answer

(C) The reaction starts with $1$-bromo-$3$-chlorobenzene. When treated with $Mg$ in dry ether $(Et_2O)$,the more reactive $C-Br$ bond undergoes Grignard reagent formation to yield $3$-chlorophenylmagnesium bromide as intermediate $(A)$. $(A) = 3-Cl-C_6H_4-MgBr$. Next,this Grignard reagent reacts with acetaldehyde $(CH_3CHO)$ followed by acidic hydrolysis $(aq. NH_4Cl)$. The nucleophilic attack of the aryl group on the carbonyl carbon of $CH_3CHO$ forms an alkoxide,which upon protonation yields a secondary alcohol. The final product $(X)$ is $1-(3-chlorophenyl)ethanol$.

In the following reaction,the compound $(X)$ is ............ .
