Question

Why LIF is insoluble in water but CSF is soluble in water

Answer 1

Answer:

i think this will help

please mark my answer as brainliest

Explanation:

LiF is almost insoluble in water due to high lattice energy. But LiCl is soluble in water due to high hydration energy of Li+ ion.

as you know, according to Fazan's law ,

covalent character increases when increases the size of anion , that's why LiCl is soluble in acetone ( covalent compound ) but LiF is insoluble in acetone .

order of covalent characters are : LiF < LiCl < LiBr < LiI
