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

Question

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 (A) Both A and R are correct and R is the correct explanation of A (B) A is not correct but R is correct (C) Both A and R are correct but R is NOT the correct explanation of A (D) A is correct but R is not correct

Be has less negative value compared to other AEM. However it's reducing nature is due to large hydration energy associated with the small size of Be 2+ ion and relatively large value of the atomization enthalpy of metal.

Both $A$ and $R$ are correct and $R$ is the correct explanation of $A$

$A$ is not correct but $R$ is correct

Both $A$ and $R$ are correct but $R$ is NOT the correct explanation of $A$

$A$ is correct but $R$ is not correct

$B e$ has less negative value compared to other AEM. However it's reducing nature is due to large hydration energy associated with the small size of $B e^{2 +}$ ion and relatively large value of the atomization enthalpy of metal.

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

A is not correct but R is correct
