Chemical Properties of Aromatic Nitro Compounds - Electrophilic substitution
Because - NO2 group is deactivating and m-directing, electrophilic substitution (halogenation, nitration and sulphonation) in simple aromatic nitro compounds (for example nitrobenzene) is extremely difficult as compared to that in benzene. Therefore vigorous reaction conditions are utilized for such reaction and the new group enters the m-position.
