The similarities and differences between van der Waals interactions and hydrogen bond. Concept introduction: Hydrogen bond is formed when a positively charged H atom held in one molecule by a polar covalent linkage comes close to a negatively charged atom belonging to another molecule. Van der Waals bond is a weak, short range, attractive force that forms because of the random distributions of electrons in an atom or molecule, which is not symmetrical and leads to a dipole.
