  2. B \(Na^+> Li^+ > K^+ > Rb^+ > Cs^+\)
  3. C \(Na^+ > Li^+ > K^+ > Cs^+ > Rb^+\)
  4. D \(Li^+ > Na^+ > K^+ > Rb^+ > Cs^+\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(Li^+ > Na^+ > K^+ > Rb^+ > Cs^+\)

Step-by-step Solution

Detailed explanation

Hydration enthalpy depends upon ionic potential (charge/size). As ionic potential increases hydration enthalpy increases \({\Delta _{hyd}}{H^o} \propto \frac{q}{r}\)
