$o$-dibromobenzene

Vedclass · Answer

(A) The number of isomers formed upon nitration depends on the number of non-equivalent positions available in the benzene ring for electrophilic substitution.For $o$-dibromobenzene ($1,2$-dibromobenzene),there are $3$ non-equivalent positions available for nitration,yielding $3$ isomers.For $m$-dibromobenzene ($1,3$-dibromobenzene),there are $4$ non-equivalent positions available,yielding $4$ isomers.For $p$-dibromobenzene ($1,4$-dibromobenzene),there is only $1$ non-equivalent position available,yielding $1$ isomer.Since the question states that $3$ isomers were obtained,the original compound must be $o$-dibromobenzene.

An aromatic compound of molecular formula $C_6H_4Br_2$ was nitrated,and three isomers of formula $C_6H_3Br_2NO_2$ were obtained. The original compound is:
