Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R. Assertion A : Benzene is more stable than hypothetical cyclohexatriene. Reason R : The delocalized π electron cloud is attracted more strongly by nuclei of carbon atoms. In the light of the above statements, choose the correct answer from the options given below.

  1. Both A and R are correct but R is NOT the correct explanation of A
  2. Both A and R are correct and R is the correct explanation of A
  3. A is true but R is false
  4. A is false but R is true

Correct answer: Both A and R are correct and R is the correct explanation of A

Solution

Benzene's stability arises from its delocalized π electrons, which are evenly distributed across the carbon atoms, leading to resonance stabilization. This delocalization results in a stronger attraction of the electron cloud to the nuclei, thus explaining why benzene is more stable than cyclohexatriene.
