JEE Main Chemistry question

Benzene fails to undergo addition reactions as readily as alkenes because

(A)It has no -electrons
(B)Addition would destroy the delocalised aromatic -system, which is thermodynamically very stable (large resonance/delocalisation energy)Correct
(C)Benzene is non-planar
(D)Benzene has only -bonds

Answer: (B)

Solution

Benzene's six -electrons are delocalised over the ring, giving it a substantial resonance (delocalisation) energy (~36 kcal/mol relative to a hypothetical cyclohexatriene). Any addition
