      So the ease of adsorption is directly proportional to the charge density and hence inversely proportional to the hydrated size and hence directly proportional to the unhydrated size? Do you agree

    At 1:07:44, the question is asking about the easy of adsorption of HYDRATED alkali metal ions yes hydrated so in aqueous condition the hydration of Li+ is more so it's size will increase(I hope you all know that in aq. Condition the order of size becomes opp.) And agar size jyada hai toh adsorption jyada hoga kyoki use adsorb karne wala bhi large organic molecules hai R group. So sabse jyada Li+ than Na+ K+ Rb+ answer toh yahi mentioned hai pyqs mai!
