(b) Due to small size of Li^+ and F^- ions, lattice enthalpy is much higher than hydration enthalpy and hence LiF is least soluble among alkali metal fluorides.

Understanding the Solubility of LiF
The solubility of lithium fluoride (LiF) in water is influenced by multiple factors, with the most significant being its lattice enthalpy. Let's explore why option B is the correct answer.
What is Lattice Enthalpy?
- Lattice enthalpy refers to the energy required to separate one mole of an ionic compound into its gaseous ions.
- A high lattice enthalpy indicates strong ionic bonds between the ions in the solid state, making them less likely to dissolve in water.
Why LiF has High Lattice Enthalpy
- Lithium fluoride has a small ionic size due to the lithium ion (Li+), which creates a strong electrostatic attraction between Li+ and F- ions.
- This strong attraction results in a high lattice enthalpy, making it energetically unfavorable for LiF to dissociate in water.
Hydration Enthalpy vs. Lattice Enthalpy
- Although Li+ has a high hydration enthalpy, which means it can interact favorably with water molecules, this factor alone is not enough to overcome the high lattice enthalpy of LiF.
- In the case of LiF, the high lattice enthalpy outweighs the favorable hydration enthalpy, leading to its low solubility.
Conclusion
- Therefore, the solubility of lithium fluoride in water is primarily affected by its high lattice enthalpy, which makes it less soluble compared to other alkali metal fluorides.
- The other options (A, C, and D) do not significantly contribute to the low solubility of LiF, confirming that option B is indeed the correct choice.
