Chemical Properties of Aromatic Nitro Compounds
Resonance in nitrobenzene pass on a partial double bond character to the bond among carbon of benzene nucleus and nitrogen of the - NO2 group along with the result the - NO2 group is tightly bonded to the ring and hence cannot be replaced other groups, that is it is very inert.
