Detailed Solution:Li? CO? decomposes easily on heating as;
Li? CO? - (Δ)-> Li? O + CO? ↑
NaHCO? is used in dry fire extinguishers.
K is most abundant element in cell fluid.
CsI is least soluble due to smaller hydration energy of Cs? & I?

Li+ has the highest hydration enthalpy.
Hence it is most hydrated
Therefore, Correct order of hydrated radii is Cs+ < Rb+ < K+ < Na+ < Li+
