Hydrogen bonding, a specific type of dipole-dipole interaction, occurs in molecules where hydrogen is directly bonded to a highly electronegative atom (N, O, or F). However, all molecules, regardless of the type of intermolecular forces they exhibit, also experience dispersion forces (also known as London dispersion forces). These are the weakest intermolecular forces and arise due to the momentary distribution of electrons leading to temporary dipoles. Therefore, even molecules with hydrogen bonding will also exhibit dispersion forces.
