Vedclass · Answer

(D) Hydration energy is directly proportional to the charge density of the ion,which is defined as the ratio of charge to size $(Charge/Size)$.For cations,as the charge increases and the size decreases,the hydration energy increases.Comparing $Al^{+3}$,$Mg^{+2}$,and $Na^{+}$: All are isoelectronic with the neon configuration,but $Al^{+3}$ has the highest charge and smallest size,followed by $Mg^{+2}$ and then $Na^{+}$.Therefore,the correct order is $Al^{+3} > Mg^{+2} > Na^{+}$.

Which of the following represents the correct order of hydration energy?
