Which of the following compounds would be expected to be more soluble in hexane (C₆H₁₄)?

Question

Quizplus · Accepted Answer

Compounds with weaker intermolecular forces tend to be more soluble in nonpolar solvents such as hexane. Out of the given compounds, I has the smallest molar mass, and thus the weakest intermolecular forces. This makes it the most soluble in hexane. II, III, and IV have progressively larger molar masses and thus stronger intermolecular forces, making them less soluble in hexane.
