Water is described as being polar because it has a slight charge difference across the different poles of the molecule
This charge difference across the molecule (dipole) allows water to form weak associations with other polar molecules
The dipolarity of a water molecule enables it to form polar associations with other charged molecules (polar or ionic)
Water can form hydrogen bonds with other water molecules (between a δ+ hydrogen and a δ– oxygen of two molecules)
This intermolecular bonding between water molecules gives water distinct properties not seen in other substances:
