Intermolecular forces of attraction strongest to weakest?

From strongest to weakest, the intermolecular forces rank in the following way:

• Strongest: Hydrogen . This occurs when contain ##"O"-"H"##, ##"N"-"H"##, or ##"F"-"H"## bonds. Though referred to as "hydrogen bonding", it's not a real bond but just a really strong intermolecular force.

• Less strong: Dipole-dipole forces. This takes place when polar compounds are attracted to one another.

• Weakest: London Dispersion Forces. This takes place when temporary dipoles on nonpolar molecules attract one another.

Note that intramolecular forces like covalent and ionic bonding are still much stronger than any form of intermolecular bonding.
