Vedclass · Answer

(C) The $-NH_2$ group is an ortho/para directing group due to its strong $+M$ effect. During the electrophilic aromatic substitution (bromination) of aniline,the electrophile $(Br^+)$ attacks the ortho or para positions of the benzene ring to form stable arenium ions (sigma complexes).The meta position is not activated by the $-NH_2$ group,and the arenium ion formed by the attack of an electrophile at the meta position is significantly less stable because the positive charge cannot be delocalized onto the nitrogen atom.Among the given options,the structure representing the meta-substituted arenium ion is not involved in the major pathway of the reaction. Based on the provided options,the structure that does not represent a valid resonance-stabilized arenium ion intermediate for ortho/para substitution is the one corresponding to the meta attack.

The arenium ion which is not involved in the bromination of aniline is:
