Which of the following has highest hydration energy -

A

`MgCl_2`

B

`CaCl_2`

C

`BaCl_2`

D

`SrCl_2`

Text Solution

Verified by Experts

The correct Answer is:
A
Smaller sized and highly charged metal ions have higher hydration energy. Therefore, order of hydration energy will be- `Be^(2+) gt Mg^(2+) gt Ca^(2+) gt Sr^(2+) gt Ba^(2+)`
