In contrast, oxygen is a simple covalent molecule. The three types of attraction are van der Waals forces, permanent dipole-dipole forces, and hydrogen bonding. This question will compare the three molecules, A - C shown below. This is why simple covalent molecules have much lower melting and boiling points than ionic substances, metals, and giant covalent structures. Instead, one atom could attract the pair more strongly than the other. Identify the predominant intermolecular force in each of these substances. The electronegative atom must be F, N or O. But as the difference in electronegativity increases, the bond becomes MORE polar.

Note: If there is more than one type of intermolecular force that acts, be sure to list them all, with a comma between the name of each force. Ion-dipole forces 5. For temporary dipole forces, we learned that they are temporary (due to the uneven distribution of the electron cloud). Answer (1 of 3): Have you heard of intermolecular hydrogen bonding.? Dipole-dipole interactions are inversely proportional to 3 r d power of the distance whereas dipole-induced dipole interaction are inversely proportional to the sixth power of intermolecular distances. A more electronegative atom will pull the pair of electrons in the bond towards itself, becoming partially negatively-charged, leaving the second atom partially positively-charged. hydrofluoric acid There are three major types of intermolecular forces: London dispersion force, dipole-dipole interaction, and ion-dipole interaction.
