Explain resonance and stability of benzene.

Answer»

Solution :The actual structure of BENZENE is a combination of all these structures called RESONANCE hybride and structures contributing to this hybrid structure are known as resonance structures. Benzene is a resonance hybrid of the following resonance structures.
KEKULE's structures CONTRIBUTE to resonance hybrid to the extent of 80% hence they EXPLAIN most of the reactions of benzene. the energy difference between kekule structrure and resonance hybrid is called resonance energy which accounts for unsual stability of benzene.
