Long Answer TypeShort Answer TypeBenzene ring has three double bonds in it but is still quite stable. Explain.
Or
Why is benzene extra-ordinary stable though it contains three double bonds?
Long Answer TypeShort Answer TypeWhat is resonance energy?
It is defined as the difference in energy between the energy of the most stable of the contributing structures and energy of the actual molecule (resonance hybrid).
Resonance Energy = Energy of most stable contributing structure - Energy of resonance hybrid.
The resonance energy of benzene is approximately 150 kJ mol-1 .
