Vedclass · Answer

$(C)$ According to $IUPAC$ nomenclature rules for substituted benzenes, substituents are listed in alphabetical order.In the given compound, the substituents are chloro $(-Cl)$ and methyl $(-CH_3)$.Alphabetically, 'chloro' comes before 'methyl'.Therefore, the parent chain is benzene, and the numbering starts from the carbon attached to the chloro group to give the lowest possible locants.Thus, the correct $IUPAC$ name is $1-$chloro$-4-$methylbenzene.Option $C$ is the correct $IUPAC$ name.

The $IUPAC$ name(s) of the following compound is(are):
$[A]$ $4-$methylchlorobenzene
$[B]$ $4-$chlorotoluene
$[C]$ $1-$chloro$-4-$methylbenzene
$[D]$ $1-$methyl$-4-$chlorobenzene
