The mobility of metal ions in aqueous medium (Li+, Na+, K+, Rb+) in the electric field, follows the order
(a) Li+ > Na+ > K+ > Rb+
(b) Rb+ > Na+ = K+ > Li+
(c) Li+ < Na+ < K+ < Rb+
(d) Na+ = K+ > Rb+ > Li+

Correct answer: (c) Li+ < Na+ < K+ < Rb+
Explanation:
Down the group with decrease in positive charge tendency to get hydrated decreases and hence the size of hydrated ion decreases. Thus mobility increases.
