AIIMS 2019 Chemistry Covalent Compounds MCQ Question

MgS is primarily an ionic compound due to the significant difference in electronegativity between magnesium (Mg) and sulfur (S), resulting in strong ionic bonds that lead to lower solubility in polar solvents like H₂O. Covalent compounds, which typically have weaker intermolecular forces, tend to dissolve better in polar solvents; thus, the statement that more covalent compounds are less soluble is misleading in the context of MgS. Other options are not provided, but any that suggest MgS is highly covalent or soluble would be incorrect, as they contradict the fundamental principles of solubility based on ionic versus covalent character.
