Correct Option - 4
Detailed Solution:Lithium salts are extensively hydrated due to high hydration enthalpy of Li+
(order of polarizing power)
Similar Questions for you
Li+ has the highest hydration enthalpy.
Hence it is most hydrated
Therefore, Correct order of hydrated radii is Cs+ < Rb+ < K+ < Na+ < Li+
