No, non-polar molecules are hydrophobic because they cannot form hydrogen bonds. A good example of this would be a cell membrane. The fatty acids in the lipid bilayer are non-polar and hydrophobic, while the polar ends that face the outside and inside of the cell are hydrophilic.

∙ 13y agoNonpolar molecules are not considered hydrophilic. This is because water is a polar solvent -- basically meaning that the electric charge on the surface of the molecule is not uniform -- so there can be local "poles" of positive or negative charge. For water, the oxygen is negative and the hydrogens are positive, so in this way the molecule is like a tiny magnet.
Nonpolar molecules (like oil, gasoline, wax) have little or no such polarization, so do not have this "magnetic" behavior, which makes them unattractive to water and other polar solvents, hence the term "hydrophobic".
However "hydrophobic" is really a misnomer, because small quantities of nonpolar molecules can mix into water and remain mixed; the fat in milk is an example. Nonpolar molecules are not "phobic" of water per se. What happens it at higher concentrations, water's "magnetic" nature makes it stick more strongly to itself than to nonpolar molecules, so these get excluded from the water mass. That is one reason why oil does not mix with water, because water would rather stick to itself if given the choice...
Many molecules have regions that are polar and other regions that are nonpolar, so they can blend with both polar and nonpolar solvents. E.g. both oil and water can be mixed in alcohols, so a certain extent. Soaps and other emulsifiers have polar and nonpolar regions and thus have both hydrophilic and "hydrophobic" behavior.

Nonpolar organic molecules are good examples of?
hydrophilic compound
What polar molecules are attracted to water?
Hydrophobic molecules do not dissolve in water. This is because water is hydrophilic. Another way to say this is that lipids, which are nonpolar, cannot dissolve in water, which in polar.
What does the science term called like dissolves like mean?
"Like Dissolves Like" is a concept in chemistry discribing hydrophobic (nonpolar) and hydrophilic (polar) interactions. Polar molecules, in order to reduce unfavorable interactions that require free energy to compensate for, tend to associate with other polar molecules. Non-polar molecules, likewise, associate with other nonpolar molecules. The terms hydrophobic and hydrophilic are used to describe a molecules tendency to associate with water. Polar molecules, using the "like dissolves like" concept associate with water, while nonpolar molecules tend to reduce interactions with water.
Does nonpolar means hydrophobic or hydrophilic?
Nonpolar means hydrophobic.
Lipids are what kind of molecules because of its positive and negative poles?
AnswerLipids are considered amphipathic because they contain both hydrophilic (polar) and hydrophobic (nonpolar) components.yea...i second dat. :)

What are molecules that do not have opposite charged ends?
Molecules that do not have oppositely charged ends are nonpolar molecules.
What is both hydrophilic and hydrophobic?
What molecules are both hydrophilic and hydropobic.
What do nonpolar molecule have?
Nonpolar molecules have no net dipoles. The most common nonpolar molecules are hydrocarbons. These are molecules made entirely of carbon and hydrogen atoms.
Which molecules are able to interact with water?
Hydrophilic molecules
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.
Is the polar end of the phospholipid plasma membrane hydrophobic or hydrophilic?
A polar molecule is hydrophilic, which means that it will easily dissolve in water. Examples of hydrophilic molecules are sugars and salts.
