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:

Options

  1. AA is true but R is false.
  2. BA is false but R is true.
  3. CBoth A and R are correct and R is the correct explanation of A.
  4. DBoth A and R are correct but R is NOT the correct explanation of A.

Correct answer

C. Both A and R are correct and R is the correct explanation of A.

Step-by-step solution

The delocalised π - electron cloud is attracted more strongly by the nuclei of the carbon atoms than the electron cloud localised between two carbon atoms. Therefore, presence of delocalised π - electrons in benzene makes it more stable than the hypothetical cyclohexatriene.
