Addition Reactions Of Benzene

Benzene behave like a saturated hydrocarbon towards addition reaction inspite of the fact it is highly unsaturated hydrocarbon. The reasons of stability of benzene towards addition reaction are given below:
1. The formation of pi - molecular orbital cause the stability of benzene and stabilization energy of pi molecular orbital in Benzene is 36 K cal/mole.
2. This stabilization energy due to the resonance is so great that pi bond of molecule will normally resist breaking. This explain the lack of reactivity of benzene towards the addition reaction.
