Vedclass · Answer

(D) The solubility of ionic compounds in water depends on their lattice energy and hydration energy. According to Fajan's rule,compounds with higher covalent character exhibit lower solubility in polar solvents like water. $MgS$ has a high degree of covalent character due to the small size and high charge density of the $Mg^{2+}$ ion,which polarizes the $S^{2-}$ ion significantly. Therefore,$MgS$ is the least soluble among the given options.
