Solution

The correct option is B (i)-high lattice enthalpy (ii)-smaller hydration enthalpy (iii)-non-polar solvents
The low solubility of LIF in water is due to its high lattice enthalpy whereas the low solubility of CsI is due to smaller hydration enthalpy of two large size ions. LIF is soluble in non-polar solvents like ethanol, acetone, etc.

Q. Solubility of an ionic compound in water is mainly dependent on:
a. Lattice enthalpy
b. Hydration enthalpy
Both these factors oppose each other, and the resultant of these factors determines the solubility of an ionic compound in water. If the lattice enthalpy has a larger value, the compound is less soluble. If the hydration enthalpy has larger value, the compound is highly soluble in water.
