Vedclass · Answer

(D) The reaction involves the bromination of valerophenone ($1$-phenylpentan$-1-$one) using $Br_2$ in the presence of $AlBr_3$ and diethyl ether $(Et_2O)$.$AlBr_3$ is a Lewis acid catalyst used for electrophilic aromatic substitution.The carbonyl group $(-CO-R)$ attached to the benzene ring is a strong electron-withdrawing group due to its $-I$ and $-M$ effects.This makes the benzene ring deactivated and meta-directing for electrophilic substitution reactions.Therefore,the electrophile $Br^+$ attacks the meta-position of the benzene ring to form $1-$($3$-bromophenyl)pentan$-1-$one as the major product.

Consider the given reaction,the product $A$ is :
