When nitrobenzene is treated with `Br_(2)` in presence of `FeBr_(3)`, the major product formed is `m-`bromo`-`nitrobenzene. Statement which is related to obtain the `m-`isomer is

Options

A. the electron density on meta-carbon is less that on ortho and para-positions
B. the intermediate carbonium ion formed after initial attack of `Br^(+)` at the meta-position is least destabilised
C. lose of aromaticity when `Br^(+)` attacks at the ortho and para-positions and not at meta-position
D. easier loss of `H^(+)` to regain aromaticity from the meta-position than from ortho and para-positions

Answer

B

Explanation

`-NO_(2)` is a m-directing and deactivating group, hence `sigma`-complex is formed by attack of `Br^(+)` at meta-position will be most stable.
