The hydration energy of `Mg^(+2)` is greater than that of

Options

A. `Al^(3+)`
B. `Na^(+)`
C. `Be^(2+)`
D. `Mg^(3+)`

Answer

B

Explanation

Hydration energy depends on the charge and radius of the ion. Greater the charge, greater is the hydration energy smaller the radius, greater is the hydration energy.
` therefore ` Hydration energy of `Mg^(2+)` > Hydration energy of `Na^(+)`
