(a)
Interpretation: The reason corresponding to the fact that the single kekule structure is consistent with the first result, but does not explain the second result is to be stated.
Concept introduction: Kekule structure of benzene consists of three alternating double and single bonds. But his structures do not take into the account of resonance structures of benzene.
(b)
Interpretation: The reason corresponding to the fact that resonance description of benzene is consistent with results of both reactions is to be stated.
Concept introduction: Kekule structure of benzene consists of three alternating double and single bonds. But his structures do not consider the resonance structures of benzene.
Most of the organic structures cannot be represented using single Lewis structure. Therefore, there exists more than one Lewis structure for representing a molecule or ion. These structures are known as resonance structures. These resonance structure combine together to give resonance hybrid that is lower in energy and is the most stable structure.
