WebDec 11, 2024 · The physical properties of a substance (e.g., its boiling point, melting point, latent heat of vaporization, etc.) will be effected by the types of intermolecular forces (e.g., H-bonding, dipole-dipole interactions, van der Waals forces, etc.) that occur in a substance. For instance, substances with weak intermolecular forces will have low ... WebIntermolecular forces (IMFs) are attractive interactions between molecules. They lead to differences and sometimes trends in various physical properties. Dispersion < Dipole-Dipole < Hydrogen-bonding < Ion-Dipole < Ion Pairing. Hydrogen- bonding (which is not bonding) is shown below in an example diagram for H2O and HF.
