Vedclass · Answer

(D) The reaction of benzene with $Br_2$ in the presence of $FeBr_3$ gives bromobenzene $(A)$.Nitration of bromobenzene with conc. $HNO_3$ and conc. $H_2SO_4$ yields a mixture of ortho-bromonitrobenzene $(B)$ and para-bromonitrobenzene $(C)$.Since ortho- and para-isomers have different boiling points due to differences in their polarity and intermolecular forces, they are separated by fractional distillation.

The method used for the separation of the mixture of products ($B$ and $C$) obtained in the following reaction is:
