These are forces of attraction between molecules such as LDF, Dipole-Dipole and H-Bonds.

These are forces of attractions within molecules such as Ionic and Covalent bonds.

These are attractions between an instantaneous dipole and an induced dipole.

These are present in ALL molecules, whether they are polar or nonpolar.

This refers to the ability of an atom or molecule can be distorted to have an instantaneous dipole.

In general, bigger molecules are easily able to do this than smaller ones.

Which molecule has a stronger London Dispersion force, Chlorine or Argon?

Which molecule has a stronger London Dispersion force, Ethane or Octane?

These Intermolecular forces are present on molecules that have permanent dipoles.

They are found in polar molecules only.

• Dipole-Dipole

• London Dispersion Forces

• Ion-Dipole

• Intramolecular Forces

The more polar the molecule, the stronger its Dipole-Dipole.

Between acetaldehyde and dimethyl ether, which has a stronger dipole-dipole?

These are special dipole-dipole interactions experienced when H is bonded to N, O, or F.

They are unusually very strong.
