The compound with molecular formula \[{{C}_{8}}{{H}_{10}}\] which will give two isomers on electrophilic substitution with \[C{{l}_{2}}/FeC{{l}_{3}}\]or \[HN{{O}_{3}}/{{H}_{2}}S{{O}_{4}}\] is

A)  p-dimethyl benzene

B)  m-dimethyl benzene

C)  o-dimethyl benzene

D)  ethyl benzene

Correct Answer: B

Solution :

Since, the compound with molecular formula, \[{{C}_{8}}{{H}_{10}}\] gives two isomers on electrophilic substitution, it must be m-xylene.
