1.	Assertion (A): Energy of resonance hybrid is equal to the average of energies of all canonical forms. Reason (R ): Resonance hybrid cannot be presented by a single structure.
Answer» Both (A ) and (R ) are correct and (R ) is the correct explanation of (A) Both (A) and R are correct but (R ) is not the correct explanation of (A) Both (A) and (R ) are not correct (A) is not correct but (R ) is correct Solution : Resonating structure of resonance is ALWAYS more stable than canonical structure. The reason for this is that delocalization of electron TAKE place with RESPECT to maximum stable canonical structure the stability of resonating structure is more because of resonance energy. The canonical FORM which is more stable its proportion in resonance structure is more because of resonance energy. The conical form which is more stable its proportion in resonance structure is more and all canonical forms according to their stability present in resonance structure. The correct statement is the value of resonance energy of resonance structure is equal to the DIFFERENCE in energy between the actual structure and the most stable of the resonatig structure. The different resonance structure contribute to the actual structure in proportion to their stability.
