The hydration energy of `Mg^(2+)` is greater than that ofA. `Al^(3+)`B. `Na^(+)`C. `Be^(2+)`D. `Mg^(3+)` |
|
Answer» Correct Answer - B `Na^(+)` has +1 unit charge . `Mg^(2+)` and `Be^(2+)` have +2 unit charge while `Mg^(2+)` and `Al^(3+)` have + 3 unit charge , therefore , hydration energy of `Al^(3+)` and `Mg^(3+)` are expected to be higher than those of `Mg^(2+)` and `Be^(2+)` , which in turn , are expected to be higher than that of `Na^(+)` . Further , the hydration energy of `Be^(2+)` is higher than that of `Mg^(2+)` due to its smaller size . In other words , hydration energy of `Mg^(2+)` is expected to be higher than that of `Na^(+)`. |
