Hi Lorena!

London forces exist in all molecules/compounds. Dipole-dipole interactions only occur among polar molecules.

Hope that helps!

London forces occur in all molecules (non-polar and polar), while dipole-dipole forces occur only in polar molecules. Dipole-dipole is the result of an attraction of a positive charge on one side of a molecule to the negative charge on another molecule. London forces occur in all molecules because electrons may gather on one side more than the other causing an "induced dipole". The link below can give a little more information on the difference.
