Rb+ > K+ > Na+ > Li+

Explanation: Hydration enthalpies of alkali metal ions decreases with the increase in ionic radii as we move down the group. Therefore, smaller is the mass of hydrated species higher is the ionic mobility in the aqueous solution. Thus, the order for ionic mobility of ions is Rb+ > K+ > Na+ > Li+
