JEE Main Chemistry question

A number of ionic compounds, e.g. , are insoluble in water. This is because:

(A)Ionic compounds do not dissolve in water
(B)Water has a high dielectric constant
(C)Water is not a good ionizing solvent
(D)These compounds have exceptionally high attractive forces in their latticeCorrect

Answer: (D)

Solution

A salt dissolves in water only when the energy released on hydrating its ions (hydration energy) exceeds the energy needed to break apart its crystal lattice (lattice energy). , and each have an unusually strong, high lattice
