It all depends on the electronegativity of the constituent atoms of the molecule. CH4 is nonpolar because carbon and hydrogen are of similar electronegativity and this means the shared electrons in the covalent bond are shared more or less equally by both elements orbitals.
Now H2O, water, is a polar molecule because the electronegativity variance is great enough that the shared electrons spend more time in the orbital around the oxygen and less time in the hydrogen's orbitals. This leads to a slightly charged molecule on both ends. A negative/positive variance.

Are lipids polar molecules?
no they are not, they are nonpolar molecules
What molecules are not attracted to polar molecules?
Nonpolar
What are the physical differences between polar and nonpolar molecules?
polarity... polar is the mid- range; nonpolar is the least polar.
A molecule with opposite charges on opposite ends?
It is called polar
Are all hydrocarbons polar molecules?
Hydrocarbons are nonpolar molecules.
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.
Is gas polar?
Some gases have polar molecules as HCl, HBr, SO2, but not all gases have polar molecules.
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.
Are lipids polar molecules?
no they are not, they are nonpolar molecules
What molecules are not attracted to polar molecules?
Nonpolar
How polar and non polar bonds affect solubility?
Molecules with many polar bonds are soluble in polar solvents.Also, molecules with none or few polar bonds (many non-polar bonds) are soluble in non-polar solvent. e.g Water is a polar solvent so substances with many polar bonds are soluble in it.
What are the physical differences between polar and nonpolar molecules?
polarity... polar is the mid- range; nonpolar is the least polar.
What molecule would mix best with water?
Polar Molecules
A molecule with opposite charges on opposite ends?
It is called polar
Are all hydrocarbons polar molecules?
Hydrocarbons are nonpolar molecules.
Is peanut butter polar or nonpolar?
nonpolar. The fat molecules in peanut butter are nonpolar, that is why peanut butter doesn't evenly mix with water, a polar substance.
Why do water molecules break up other polar molecules?
Because water is polar, so when a when a polar solute is put in it will dissolve. Like dissolves like. Polar dissolves polar. Likewise, nonpolar dissoves nonpolar.
