Question
Given below are two statements, one is labelled as Assertion A and the order 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 Be2+ but relatively large value of atomization enthalpy. In the light of the above statements, choose the most appropriate answer from the option 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.
💡 Solution & Explanation
Be has least negative SRP value in alkaline earth metal group as it has high hydration enthalpy and high enthalpy of atomisation.
