Description of this simulation
Water (H2O): Intermolecular-force finder — Hydrogen bonding, dipole–dipole, dispersion. Two lone pairs compress the H–O–H angle and leave a strong net dipole.

What this model shows — and what it simplifies
London dispersion is present in every molecule; dipole–dipole attraction requires a permanent molecular dipole, and hydrogen bonding requires hydrogen directly bonded to nitrogen, oxygen or fluorine.
Where do we see this in real life?
Intermolecular forces decide whether a substance is a gas or liquid, how it dissolves and how a drug molecule crosses a membrane.
