Do water molecules attract nonpolar molecules such as oil?
Yes, but they attract polar molecules more strongly."Hydrophobic" molecules is a misnomer. The nonpolar molecules in question are attracted to water molecules (usually more strongly than they're attracted to each other, even), but they get "shoved out of the way" by polar "hydrophilic" molecules which are even more strongly attracted to water molecules.
Why don't polar compounds mix with nonpolar compounds?
Polar compounds have poles that have a partial positive charge and a partial negative charge that attract other polar molecules. Nonpolar compounds do not have partially charged poles, so the polar substance is not attracted to them and they don't dissolve.
Are saturated Hydrocarbons non-polar?
Hydrocarbons are usually nonpolar, since their bonds line up opposite each other to cancel out any dipole moment. But in small hydrocarbons that have an alcohol group (OH), which is a polar group, a small dipole moment can result thus making the hydrocarbon polar. But in large chains hydrocarbons containing one alcohol group, the size of the hydrocarbon cancels any polarity resulting from the group out, thus the hydrocarbon is nonpolar.
Is C8H18 polar or nonpolar?
No C8H18 is nonpolar as are other hydrocarbons
Is C6H5CH3 polar?
No, it is nonpolar like other hydrocarbons.

What Can Water Not Dissolve?
Water is a universal solvent and can dissolve many substances, but it cannot dissolve non-polar substances like oil, grease, and some plastics. These substances do not have a charge and therefore do not interact well with water molecules.
What is the name the property of water in which it sticks to other substances?
The attraction between water molecules and another substance is called adhesion. An example of this phenomenon is the absorption of water by a towel. Water molecules are also attracted to each other by cohesion. Adhesion and cohesion of water are both caused by the polarity of water molecules. Molecules are said to be polar if they have opposite electrical charges at different ends of the molecule. Nonpolar molecules have none or evenly distributed charges (oil is an example of a nonpolar substance). Since opposite charges attract, water is attracted to other polar (or ionic) substances.

Is vitamin A nonpolar?
Yes, vitamin A is a type of nonpolar molecule. Like other nonpolar molecules, it is insoluble in water and soluble in fat.
Are non-polar molecules more attracted to other non-polar molecules or polar molecules?
Non-polar molecules are more attracted to other non-polar molecules.
What is in a substance that makes it hydrophobic?
Substances are hydrophobic because they are nonpolar. Nonpolar molecules are made up of elements with little difference in their electronegativities so they do not have charges or partial charges. Water is a polar molecule so it tends to be attracted to other molecules that are polar as well. This is often summed up as "like attracts like". Some examples of hydrophobic molecules include fats and oils which are nonpolar because they have large hydrophobic hydrocarbon chains.

Are poler substances attracted to the other poler substances or to the nonpoler substances?
Polar molecules are attracted to other polar molecules with an opposite charge.
Is C8H18 polar or nonpolar?
No C8H18 is nonpolar as are other hydrocarbons
What dissolve in oil?
