Which of the following sets will have highest hydration energy and highest ionic radii

A

Na and Li

B

Li and Rb

C

K and Na

D

Cs and Na

Text Solution

Verified by Experts

The correct Answer is:
B
Smaller the size, greater is the hydration enthalpy. So, Li will have highest hydration enthalpy. Down the group ionic radius increases, so Rb will have highest ionic radius.
