Question
The correct has high electron affinity ?
Options
A.Li+ > Na+ > K+ > Rb-
B.Rb+ > K+ > Na+ > Li+
C.Na+ > K+ > Li+ > Rb+
D.K+ > Rb+ > Na+ > Li+
Solution
hydration energy ∝ 
In a group, size increase on going down the group from top to bottom i.e.,
Rb+ > K+ > Na+ > Li+
∴ Increasing order of hydration energy Li+ Na+ > K+ > Rb+
