Vedclass · Answer

(C) In an aqueous medium,alkali metal ions get hydrated. The extent of hydration depends on the size of the ion; smaller ions have higher charge density and get more hydrated.The order of hydrated ionic radii is: $Li^{+} > Na^{+} > K^{+} > Rb^{+} > Cs^{+}$.Since the hydrated ion of $Li^{+}$ is the largest,it moves the slowest in an electric field.Therefore,the correct order of ionic mobility is: $Li^{+} < Na^{+} < K^{+} < Rb^{+}$.
