`Li^(+)` ion has maximum degree of hydration. Why?

Which one of the following alkali metal ion posses maximum degree of hydration (A) Li^(+) (B) Na^(+) , c) K^(+) (D) Cs^(+)

The solubility of alkli metals salts in water is due to the fact that the cations get hydrated by water molecules. The degree of hydration depends upon the size of the cation. If the trend of relative ionic radii is Cs^(+) gt Rb^(+) gt K^(+) gt Na^(+) gt Li^(+) . What is the relative degree of hydration?

The ion which has the maximum value of hydration energy is

The ion having maximum value of hydration energy is :

Alkali metal salts ionic and soluble in water. The solubility of an ionic compound depends on (i) lattic ethalpy and (ii) hydration enthalpy. These two factor oppose each other. If hydration ethalpy is high, the ions will have greater tendency to be hydrated and therefore the solubility will be high. The smaller the cation, the greater is the degree of hydration. The reducing behaviour of alkali metals in solution is also dependent on the hydration enthalpy besides other factors. The ionic mobility of Li^(o+) is less than of the Na^(o+) ion in solution because
