this happens due to protonation of NH2 group & thus anilium ion gets +ve charge ,
this group becomes highly -R & -I electron withdrawing group hence it resists the attack
of electrophlile at ortho or para position , therefore electrophile attacks at meta position (electron rich site)...
this group is de activates the ring towards electrophile attack & hence less reactive towards
electrophilic substitution reaction ....
approve if u like my ans
