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

Answer» Correct Answer - B `-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. |
