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
Are all hydrocarbons polar molecules?
Hydrocarbons are nonpolar molecules.
What are the physical differences between polar and nonpolar molecules?
Polar molecules have an uneven distribution of electrons, leading to regions of partial positive and negative charges. Nonpolar molecules have an even distribution of electrons and no distinct positive or negative regions. This difference in electron distribution affects properties such as solubility, melting point, and boiling point between polar and nonpolar molecules.
What molecules would you expect to dissolve in water polar covalent molecules inoic molecules nonpolar convalent molecules?
ionic molecules dissolve the most. but some polar covalent molecules also do dissolve in water.
Is artificial flavor polar or nonpolar?
Artificial flavors can be either polar or nonpolar, depending on their chemical structure. Some artificial flavors may have polar functional groups (such as hydroxyl or carbonyl groups), making them polar molecules, while others may have nonpolar structures, making them nonpolar molecules.
Are lipids polar molecules?
no they are not, they are nonpolar molecules
What molecules are not attracted to polar molecules?
Nonpolar
Is hydrophilic a property that determines whether a molecule is polar or nonpolar?
Yes, hydrophilic is a property that determines whether a molecule is polar or nonpolar. Hydrophilic molecules are polar, while hydrophobic molecules are 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.
Are all hydrocarbons polar molecules?
Hydrocarbons are nonpolar molecules.
Why does non polar molecules repel water molecules?
Because it is like a magnatizing ordeal so to say and it just bounces of non polar molcuels. :)
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.
Would a non polar molecule dissolve in a polar molecule?
Nonpolar molecules tend to dissolve better in other nonpolar molecules due to similar intermolecular forces, while polar molecules dissolve better in other polar molecules. This is because like dissolves like - molecules with similar polarity tend to mix well together. Generally, nonpolar molecules do not dissolve easily in polar solvents.
Do polar and nonpolar molecules interact?
In general, polar molecules interact more strongly with other polar molecules (due to dipole-dipole interactions) and nonpolar molecules interact more with other nonpolar molecules (via London dispersion forces). However, there can be exceptions depending on the specific molecules involved and the conditions of the interaction.
If polar and nonpolar solutions are mixed together they will form what?
If polar and nonpolar solutions are mixed together, they will not mix and will form separate layers due to their different polarities. This is because polar molecules are attracted to other polar molecules, while nonpolar molecules are attracted to other nonpolar molecules.
What polar molecules are attracted to water?
Polar molecules with positively charged regions, such as ammonia and alcohols like ethanol, are attracted to water due to hydrogen bonding. Additionally, polar molecules with negatively charged regions, such as acetate ions, are also attracted to water for the same reason.
