Put in order from strongest to weakest: London Dispersion Forces, Hydrogen Bonds, Dipole-dipole interactions, ionic bonding, and covalent bonding.

  • Chemistry -

    The physical properties of biological substances depend on the intermolecular forces present. The sequence of strength from strongest to weakest force is ions > hydrogen bonding > dipole-dipole > London forces. As the strength of forces decreases, so do the melting points, boiling points, and solubility in water. Besides that, the vapor pressure and the solubility in nonpolar solvents also increases.
