1.	A resonance hybrid is always more stable than any of its canonical structures. This stability is due to delocalization of electrons.A. If both assertion and reason are true and the reason is the correct explanation of the assertion.B. If both assertion and reason are true but reason is not the correct explanation of the assertion.C. If assertion is true but reason is falseD. If assertion is false but reason is true.
Answer» Correct Answer - A (a) We know that a resonance hybrid or the actual molecule is always more stable than any of its canonical structures which is also called hypothetical or imaginary structures. The stability is due delocalization of electrons and is measured in terms of resonance energy or delocalization energy, it is defined as the difference in internal energy of the resonance hybrid and the most stable canonical structure. Therefore, both the assertion and reason are true and the reason is a correct explanation of the assertion.
