Nonpolar
Polar Molecules
When there attracted to the charged wand they are polar.
Because water molecules are polar covalent, one side is slightly negative and the other slightly positive. Thus, they are attracted to one another.
When soap is mixed with octane the non-polar ends of the soap molecules are attracted with induced-dipole induced-dipole attractions to the non-polar octane molecules. The octane molecules repel the polar ends of the soap and the soap molecules form inverted soap bubbles that attract polar molecules like water.
Water molecules are polar This causes them to be attracted to the cell surface, which is also polar in nature
Non-polar molecules are more attracted to other non-polar molecules.

Polar molecules are attracted to other polar molecules with an opposite charge.
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.
Fats and oils are nonpolar, so they will remain separate from molecules of a polar solvent such as water. Sodium and chloride ions are attracted to charged regions on molecules of polar solvents such as water.
because water is highly polar and Br2 is non-polar so the molecules in the water are more attracted to each other. But methylene chloride is non-polar so its molecules are no more strongly attracted to other methylene chloride molecules than they are to Br2 molecules. Since all of the forces are weak, the substance can dissolve.

Water molecules won't form a solution (are not miscible) in oil. The reason is that water molecules are polar, and oil molecules are not. Water molecules, in an environment of oil, are attracted to each other, and this polar bonding excludes the oil molecules.
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.
