Water is a polar molecule. since oxygen has a slight negative charge and each hydrogen has a slight positive charge, this allows water molecules to form covalent bonds with other water molecules. form van der waals bonds with other water molecules. form hydrogen bonds with other water molecules. form ionic bonds with other water molecules.

Form hydrogen bonds with other water molecules

Explanation:

Since the molecules of water have dipoles, they act like magnets attracting opposites. The hydrogen end (partially positive)of one molecule attracts the oxygen end (partially negative) of the next molecule. The dipole-dipole forces between these molecules are what form the hydrogen bonds because it involves a hydrogen atom. Hydrogen bonds are a part of Van der Waals forces.
