Vedclass · Answer

(C) The degree of hydration of ions depends on their charge density. Smaller ions have higher charge density,which leads to stronger attraction for water molecules,resulting in a higher degree of hydration. Among alkali metal ions,the ionic size increases down the group: $Li^{+} Therefore,the degree of hydration decreases as the ionic size increases. The correct order of hydration is $Li^{+} > Na^{+} > K^{+} > Rb^{+} > Cs^{+}$,which is equivalent to $Cs^{+} < Rb^{+} < K^{+} < Na^{+} < Li^{+}$.

The correct order of degree of hydration of $M^{+}$ ions of alkali metals is
