Key Points

The difference in electronegativities between oxygen and hydrogen atoms creates partial negative and positive charges, respectively, on the atoms.

Water molecules attract or are attracted to other polar molecules.

Molecules that do not dissolve in water are known as hydrophobic (water fearing) molecules.

Key Terms

hydrophilic: having an affinity for water; able to absorb, or be wetted by water

hydrophobic: lacking an affinity for water; unable to absorb, or be wetted by water

polarity: The intermolecular forces between the slightly positively-charged end of one molecule to the negative end of another or the same molecule.
