When nitrobezene is treated with Br_2 in the presence ofFeBr_2 the major product formed is m-bromonitro-benzene . Statements which are related to obtatining the m-isomer are :

Answer»

The electron densitty on meta-carbon is more than that on ortho-and para -positons
The intemediate CARBONIUM ion formed after intial attakc of ` Br^(o+)` at the meta-position is LEAST destabnilise
Loss of aromaticity when ` Br^(o+)` attacks at the orth- and para -POSITIONS and not at meta-position.
Easier loss of ` H^(o+)` to regain aromaticity from the meta-position than FROMM the ortho- and para-positions
