HYDROPHOBIC FORCES

Both actually. Water is technically a polar solvent that has a dipole, with the oxygen being most electronegative and attracting the electrons. This causes the hydrogen atoms to temporarily have a lesser charge, and this in turn causes the weak hydrogen atoms to become attracted to the oxygen of other water molecules nearby.

Any substance of molecules that have hydrophobic effect meaning is that molecules/substances have fear of water. For example of mixing water with oil. Yes polarity is important but unusual and/or important properties of water include: high polarity, hydrogen bonding, cohesion, adhesion, high specific heat, and high heat of vaporization. water is, by far and away, the most common molecule that exists as a liquid at typical ambient Earth temperatures. Water is a powerful dissolver of polar ions and molecules (polar solvent), and a similarly powerful excluder of nonpolar molecules. These properties of water are all important and/or crucial to the existence of life as we know it.

timorito, please mark this as solved.
