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

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 destablized.
Loss of aromaticity when `Br^(+)` attacks at the ortho and para positions and not at meta position
Easier loss of `H^(+)` to regain aromaticity from the meta position than from ortho and para positions.
