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 $$\pi$$ 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:
Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion A : Beryllium has less negative value of reduction potential compared to the other alkaline earth metals.
Reason R : Beryllium has large hydration energy due to small size of Be$$^{2+}$$ but relatively large value of atomization enthalpy
In the light of the above statements, choose the most appropriate answer from the options given below :
