Verified By Collegedunia

The Correct Option is D

Solution and Explanation

Higher is the hydration energy, more will be the solubility in water. If the cations have different charge then the one with higher charge will have higher hydration energy. Among

CsClO_{4}, NClO_{4}

and

LiClO_{4}

all of the cations have

+1

charge, so for comparing hydration energy size factor will be considered Smaller is the size more will be the hydration energy. Thus, among all cations

Li^{+}

is smallest in size. Hence ,

LiClO_{4}

is most soluble in water
