Vedclass · Answer

(B) The reaction of $1,4-$dimethylbenzene ($p-$xylene) with anhydrous $AlCl_{3}$ and $HCl$ is an example of an isomerization reaction. Under these acidic conditions, the methyl groups undergo rearrangement to form the more thermodynamically stable isomer. $1,3-$dimethylbenzene ($m-$xylene) is more stable than $1,4-$dimethylbenzene ($p-$xylene) due to the reduced steric hindrance and electronic factors in the meta-substituted product. Therefore, the reaction produces $1,3-$dimethylbenzene.
