When nitrobenzene is treated with Br_(2) in presence of FeBr_(3) , the major product formed is m-bromonitrobenzene. Statements which are related to obtain m-isomer are:

Answer»

The electron DENSITY on meta carbon is more than that on ORTHO and para positions
The intermediate (CARBONIUM ION) formed after initial attack of `Br^(+)` at the meta position is least destabilized.
Loss of aromaticity when `Br^(+)` attacks at the ortho and para positions and not at meta position.
Easier loss of `H^(+)` to regain AROMATICALLY from the meta position than from ortho and para positions.

Solution :The intermediate carbonium ion formed after initial attack of `Br^(+)` at the meta position is least destabilized. Hence(B) is the correct answer
