Vedclass · Answer

(D) The solubility of ionic compounds in water is determined by the balance between lattice enthalpy and hydration enthalpy.For alkali metal fluorides,the lattice enthalpy decreases significantly as the size of the cation increases from $Li^+$ to $Cs^+$.Since lattice enthalpy is inversely proportional to solubility,the solubility increases as the size of the alkali metal cation increases.Therefore,the correct order of solubility is $LiF < NaF < KF < RbF$.
