- Benzene is highly unsaturated molecule but despite of this feature, it does not give addition reaction.
- The actual structure of benzene is represented by the resonance hybrid which is the most stable form of benzene than any of its resonance structures.
- This stability due to resonance (delocalization of π electrons) is so high that π-bonds of the molecule becomes strong and thus, resist breaking.
Thus, benzene does not prefer to undergo addition reactions.
