Question
Chemistry Question on d block elements
A compound with delocalised electrons is more stable than that compound would be if all its electrons were localised. The extra stability, a compound gains as a result of having delocalised electrons, is called delocalisation energy.
If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion
If both Assertion and Reason are true but the Reason is not the correct explanation of the Assertion
If Assertion is true but Reason is false
If both Assertion and Reason are false
If both Assertion and Reason are true but the Reason is not the correct explanation of the Assertion
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.
