Intermolecular Forces

Weak attractions between molecules

Weaker then Ionic and covalent bonds

Responsible for determining whether a compound is a solid liquid or gas

The weakest force between molecules

Includes both dipole interactions and dispersion interactions

Found between both polar and non-polar bonds

The only forces found in non-polar molecules

When two dipole molecules interact with each other through space.

The partially negative portion of one polar molecule is attracted to the partially positive portion of a second molecule.

Can not happen between non-polar molecules

Attractive forces in which a hydrogen covalently bonded to a very electronegative atom

Oxygen, Nitrogen and Fluorine

Hydrogen- The only chemically reactive element with valence electrons that are not shielded from the nucleus by other electrons.

The strongest intermolecular forces
