QJEEM23Che6a5: JEE Main 2023 Chemistry - Class 11 JEEM23Che6a5 Solution: Given below are two statements, one is labelled as Assertion A…
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 delocalised 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:
Multiple Choice Options
- A A is true but R is false
- B Both A and R are correct and R is the correct explanation of A
- C Both A and R are correct but R is NOT the correct explanation of A
- D A is false but R is true
Step-by-Step Verified Solution
Benzene is more stable than hypothetical cyclohexatriene due to the delocalization of electrons in the π electron cloud of the aromatic ring. This delocalization of electrons leads to a more stable electronic configuration in benzene, as the electrons are shared more evenly between all six carbon atoms in the ring. This is in agreement with Assertion A.
Reason R is also correct, as the delocalized π electron cloud in the aromatic ring is attracted more strongly by the nuclei of the carbon atoms. This is due to the fact that the π electrons in the ring are more spread out and are not localized to a single atom, which makes them more attracted to the positively charged nuclei of the carbon atoms. This explanation supports Assertion A.
