All the resonance forms for the sigma complexes that correspond to bromination of aniline at the ortho, meta and para positions are to be drawn. Concept introduction: Nitrogen atom of − NH 2 group in aniline contains a nonbonding pair of electrons. It is a strong activating group. It makes the aromatic ring more electron rich as compared to anisole. The sigma complex formed during the electrophilic substitution reaction is resonance stablised due to non bonding electrons of nitrogen. Aniline give ortho and para substituted products. To determine: All the resonance forms for the sigma complexes that correspond to bromination of aniline at the ortho, meta and para positions.
