Assertion: A compound with delocalised electrons is more stable than that compound would be if all its electrons were localised. Reason: The extra stability, a compound gains as a result of having delocalised electrons, is called delocalisation energy.

Assertion: A compound with delocalised electron is more stable than that compound would be if all its electrons were localised. Reason: The extra stability, a compound gains as a result of having delocalised electrons, is called delocalisation energy Delocalisation of electrons brings stability among the compounds. It is the result of resonance. We can take the example of benzene ring which is exceptionally stable due to the resonance. However, delocalisation energy is also called resonance energy. It is the extra energy provided by delocalised electrons that are extended over the whole covale
