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.

View answer and explanation

Correct option: C

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

Option C (Both A and R are correct and R is the correct explanation of A) is correct because Beryllium's less negative reduction potential is due to its high atomization and ionization enthalpies, coupled with a large hydration energy.
