For small molecules, which of the following usually is the weakest intermolecular interaction?

Question

Quizplus · Accepted Answer

London dispersion forces are the weakest intermolecular interaction for small molecules. This is because they occur due to temporary fluctuations in electron density, which results in a very weak attraction between neighboring molecules. Covalent bonding is a much stronger type of bonding, while dipole-dipole interactions and hydrogen bonding also involve permanent dipoles and hydrogen atoms, respectively, and are therefore stronger than London dispersion forces.
