    As the charge to size ratio of the cation increases, the degree of hydration increases. Hence, the ionic mobility decreases..This happens in case of polar solvent

    So the order is wrong which I have asked

    eduncle-logo-app

    yes shristy....more hydrated means it is surrounded by more h20 molecules...so less is the ionic mobility
