QJEEM19Ch3368: JEE Main 2019 Chemistry - Class 11 JEEM19Ch3368 Solution: The correct order of hydration enthapies of alkali metal ions…
The correct order of hydration enthapies of alkali metal ions is :
Multiple Choice Options
- A Li+ > Na+ > Cs+ > Rb+
- B Na+ > Li+ > K+ > Cs+ > Rb+
- C Na+ > Li+ > K+ > Rb+ > Cs+
- D Li+ > Na+ > K+ > Rb+ > Cs+
Step-by-Step Verified Solution
Hydration energy/enthalpy
Smaller the size more is hydration energy.
Li+ having minimum radius so maximum hydration energy.
Correct order is :
Li+ > Na+ > K+ > Rb+ > Cs+
Li+ having minimum radius so maximum hydration energy.
Correct order is :
Li+ > Na+ > K+ > Rb+ > Cs+
