Choose the correct statement from the ones given below for two anilium in:

1. II is not an acceptable canonical structure because carbonium ions are less stable than ammonium ions

2. II is not an acceptable canonical structure because it is non-aromatic

3. II is not an acceptable canonical structure because the nitrogen has 10 valence electrons

4. II is an acceptable canonical structure

When nitrobenzene is treated with Br₂ in presence of FeBr₃, the major product formed is m-bromonitrobenzene. Statements which are related to obtain the m-isomer are:

(1) the relative electron density on meta carbon is more than that of ortho and para positions

(2) loss of aromaticity when Br⁺ attacks at the ortho and para positions and not at meta position

(3) easier loss of H⁺ to regain aromaticity from the meta positions than from ortho and para positions

(4) none of the above
