An unknown substance dissolves readily in water but not in benzene (a nonpolar solvent).Molecules of what type are present in the substance?

Question

Quizplus · Accepted Answer

The fact that the substance dissolves readily in water, which is a polar solvent, suggests that the substance must be polar. Nonpolar substances do not dissolve in polar solvents like water, and benzene is a nonpolar solvent. Therefore, the substance must be polar in order to dissolve in water and not in benzene.
