The diagram below shows a group of water molecules.

Water is shown as an upper O with superscript delta minus, bonded below left and right to upper H atoms with superscripts delta plus. The right H is bonded with a dotted line to the O in an identical atom below to the right. The right H of the second molecule is bonded with a dotted line to the O of a third molecule, which is reversed top to bottom from the other two.

The water molecules in the diagram are attracted to each other by
ionic bonds.
hydrogen bonds.
London dispersion forces.
dipole-induced dipole interactions.
