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 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
- AA is true but R is false.
- BA is false but R is true.
- CBoth A and R are correct and R is the correct explanation of A.
- 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 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 electrons in benzene makes it more stable than the hypothetical cyclohexatriene.
