What kind of chemical structure does water have?

The formula of water is H2O, and one water molecule is composed of two hydrogen atoms and one oxygen atom combined with polar covalent bonds through a common electron pair. The molecular structure of water is asymmetrical. Three atoms are separated into three corners of a triangle. The two HO bonds form an angle of 104° and 45′. Therefore, water molecules belong to polar molecules and there is an orientation force between water molecules. Force, dispersive force and hydrogen bonding have a strong intermolecular attraction.
