Assertion (A): Beryllium compounds are covalent in nature.
Reason (R ): The size of `Be^(2+)`ion is larger in compariso to the radii of the other divalent ions of alkaline earth metals.

Options

A. If both `(A)` and `(R )` are correct and `(R )` is the correct explanation of `(A)`.
B. If both `(A)` and `(R )` are correct, but `(R )` is not the correct explanation of `(A)`.
C. If `(A)` is correct, but `(R )` is incorrect.
D. If `(A)` is incrrect, but `(R )` is correct.

Answer

C

Explanation

Correct reason: Due to small size and high charge on `Be^(2+)` polarising power of `Be^(2+)` is high and it forms convalent compounds.
