Explain how hydrogen bonding occurs between molecules of water.

Hydrogen Bonding occurs between 2 adjacent molecules of H2O.

The polar covalent bond between oxygen and hydrogen creates negative and positive partial charges respectively.

There is a weak intermolecular force of attraction between the patially positively charged hydrogen atom of one molecule and the partially negativly charged oxygen atom of an adjacent molecule.

The hydrogen bond occurs in a striaght line, so that the covalent bonds of both molecules are in line.
