Which of the following is NOT a type of Van der Waals force?

Ionic bonding is distinguished from Van der Waals forces by the nature of the interactions involved. Van der Waals forces are relatively weak intermolecular attractions that arise from temporary or permanent dipoles in molecules, while ionic bonding involves the electrostatic attraction between positively and negatively charged ions, which is a much stronger and fundamentally different type of interaction.

London dispersion forces arise from induced dipole moments due to the presence of electrons in motion, and permanent dipole-permanent dipole interactions occur between molecules that have permanent dipoles due to differences in electronegativity. Hydrogen bonding, while a strong type of dipole-dipole interaction, is still classified under Van der Waals forces because it involves hydrogen atoms bonded to highly electronegative atoms such as oxygen, nitrogen, or fluorine.

The correct answer reflects that ionic bonding does not fall under the umbrella of Van der Waals forces, which are characterized by more transient and weaker interactions.
