Short answer: See [for a polar example] the molecule Water, H2O: occasionally it will 'disassociate' into the H+ and the OH- IONS, yet mostly it exists as an electrically neutral H2O. As in reality, the two H+'s are on one end of the molecule while the other end of the molecule is occupied by the electronegative oxygen atom, so two H+ & one O 2- make up a neutral atom that is electrically active at its ends, or poles; or polar.
Nonpolar? Remove oxygen; leave just carbon and hydrogen, which provides a balanced or nonpolar [if any] charge distribution.
Do Not Separate the two, Tao says no. What gives Lipids (plain oils -from plants- and fats -from animals-, phospholipids, glycolipids etc.) their great powers is that they possess a polar [or charged by the presence of an acid group - COO- ] hydrophillic head AND a neutral [no charges] non polar ( only CH2 s ) hydrophobic tail.
This is why lipids are also known as fatty-acids.

Is bacteria and virus polar or non polar?
Bacteria and viruses are not molecules and are neither polar nor nonpolar. The contain both polar and nonpolar molecules.
Is flour made up of polar or nonpolar molecules?
Flour has both polar and non-polar molecules in it. However, most cooking flours have more non-polar molecules, which is why they distribute more evenly in non-polar liquids (like melted butter) than polar (water).
Is CH2 polar or non polar?
CH2 does not exist as a molecule. There are, however, C2H2 and CH4, both of which are nonpolar.
Do non polar molecules have both negative or positive ends?
Some but not most non polar molecules have both negative and positive "ends" to their individual bonds. Examples include tetrafluoromethane. By definition, however, a non-polar molecule does not have negative and positive ends to an entire molecule.
Are non-polar molecules hydrophilic?
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.
Is bacteria and virus polar or non polar?
Bacteria and viruses are not molecules and are neither polar nor nonpolar. The contain both polar and nonpolar molecules.
Is flour made up of polar or nonpolar molecules?
Flour has both polar and non-polar molecules in it. However, most cooking flours have more non-polar molecules, which is why they distribute more evenly in non-polar liquids (like melted butter) than polar (water).
Is CH2 polar or non polar?
CH2 does not exist as a molecule. There are, however, C2H2 and CH4, both of which are nonpolar.
What factor determines if two liquids will be miscible or immiscible?
Molecules that do not dissolve in other molecules that are similar. If the molecules are not similar, they will not mix. Therefore, you have an immiscible liquid. Polar solvents will only dissolve polar compounds. (e.g. NaCl in H2O soln) Nonpolar solvents will only dissolve nonpolar compunds. (e.g Vitamin A in an oil) However, certain solvents are miscible with both polar and nonpolar solvents. An example of this would be ethanol (CH3CH2OH), which is miscible with water(polar) and hexane(nonpolar).
Are lipids polar?
Lipids, both fats and oils, have a polar head and a non-polar tail.
Is soap polar nonpolar?
Soap is actually both. It is similar to a phospholipid in that it has a polar head and a nonpolar tail.
What type of organic molecule requires the action of emulsifiers to be sucessfully digested?
Fat molecules. Water molecule is polar, and therefore water is a good solvent for other polar molecules, dissolving them when they come in contact with one another. Water is not a good solvent for nonpolar molecules, such as fats. A fat has no polar grups to interact with water molecules. An emulsifier, however, can cause a fat to disperse in water. An emulsifier contains molecules with both polar and nonpolar ends. When the nonpolar ends interact with the fat and the polar ends interact with the water molecule, the fat disperses in water, and an emulsion results.
Are oil-base paints polar nonpolar or both?
Both
What are emulsions?
A polar and a nonpolar substance being made miscible together by another substance that has both polar and nonpolar characteristics.
Is vinegar polar nonpolar or both?
Acetic acid (CH3COOH) has a polar molecule.
Do non polar molecules have both negative or positive ends?
Some but not most non polar molecules have both negative and positive "ends" to their individual bonds. Examples include tetrafluoromethane. By definition, however, a non-polar molecule does not have negative and positive ends to an entire molecule.
Can polar molecules and molecules that have chargers sneak through the nonpolar middle portion of the phospholipid bilayer?
No, they are not. Micelles are formed by amphipathic molecules, that is molecules having both poplar and nonpolar regions, such as phospholipids or fatty acids. The polar region stays to the outside of the sphere as it can interact with water or some other polar solvent and the nonpolar regions are forced to the center.
