Question

The low melting point and the high solubility of $LiCl$ in organic solvents is due to:

• A. Covalent nature because of polarising power of small $L{i}^{+}$ on $C{l}^{-}$
• B. Very low lattice energy
• C. Low hydration energy of $L{i}^{+}$ in water
• D. Low hydration energy of $C{l}^{-}$ in water

Answer 1

The correct option is A Covalent nature because of polarising power of small $L{i}^{+}$ on $C{l}^{-}$

Though $LiCl$ has a high lattice energy, due to the polarisation of $C{l}^{-}$ by $L{i}^{+}$, it has covalent character. Hence, it has low melting point and high solubility in organic solvents.
