HUMAN NUTRITION

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 solutes also dissolve in nonpolar solutions without breaking any bonds within the molecule. For example, if you’re cooking, you can add some walnut oil to your olive oil for extra flavor. The molecules of walnut oil will mix in and become dispersed among the molecules of olive oil.

Detailed explanation-3: -Polar solvents will dissolve polar and ionic solutes because of the attraction of the opposite charges on the solvent and solute particles. Non-polar solvents will only dissolve non-polar solutes because they cannot attract the dipoles or the ions.

Detailed explanation-4: -Nonpolar substances are likely to dissolve in nonpolar solvents. For example, nonpolar molecular substances are likely to dissolve in hexane, a common nonpolar solvent.
