MCQ
Among the following, which has the maximum hydration energy?
- A$OH^-$
- B$NH^+_4$
- C$F^-$
- ✓$H^+$
Hydration energy depends on the charge of the ion and the ionic radius. Higher the charge and smaller the size, greater the hydration energy. $H ^{+}$has the smallest size and hence has the maximum hydration energy among the four.
