उत्तर
The solubility order for alkali metal fluoride in water is LiF < NaF < KF < RbF.
Explanation:
The higher the lattice enthalpy, the lower the solubility, i.e.
lattice enthalpy `∝ 1/"Solubility"`
Since the lattice enthalpy of alkali metals follows the order:
Li > Na > K > Rb
Hence the correct order of solubility is:
LiF < NaF < KF < RbF
