An aromatic compounds X with molecular formul\[{{C}_{8}}{{H}_{10}}\]produces on nitration one mononitro derivative and three dinitro derivatives. Compound X would be

A)  ethyl benzene

B)  \[m-\]xylene

C)  \[o-\]xylene

D)  \[p-\]xylene

Correct Answer: D

Solution :

 In p-xylene, the four nuclear H-atoms are equivalent and hence, only one mononitro derivative is formed. But it gives three dinitro derivatives (2, 3; 2, 6 and 2, 5) as shown below:
