Single Choice

Which of the following is not a feature of resonance?

AIt gives extra stability to compounds
BIt gives extra bond energy to compounds
CIt reduces the stability of compounds
Correct Answer
DNone of the above

Solution

Electron delocalization lowers the potential energy of the substance and thus makes it more stable than any of the contributing structures. The difference between the potential energy of the actual structure and that of the contributing structure with the lowest potential energy is called the resonance energy.
