Detailed explanation-1: -Nonpolar substances will dissolve in nonpolar solvents. To dissolve the oil stain described in this question a nonpolar solvent such as hexane or carbon tetrachloride could be used.

Detailed explanation-2: -Nonpolar substances are likely to dissolve in nonpolar solvents. For example, nonpolar molecular substances are likely to dissolve in hexane, a common nonpolar solvent.

Detailed explanation-3: -Solvents with a dielectric constant of less than 15 are generally considered to be non-polar[4][5]. Non-polar solvents are most suitable for dissolving non-polar samples. Common non-polar solvents: Hexane. Toluene.

Detailed explanation-4: -Nonpolar solvents are not miscible in water and are therefore used to dissolve hydrophobic substances such as oils and fats. This category of solvents includes benzene, carbon tetrachloride, diethyl ether, hexane, and toluene.
