Q. 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.

AIIMSAIIMS 2009

Solution:

Delocalisation of electrons provides more stability to the compounds. The extra stability which is acquired by a compound as a result of resonance (delocalisation of electrons) is called resonance energy or delocalisation energy. Hence, statement I and II both are correct but statement II is not the correct explanation of I.
