WebIntermolecular forces are attractive forces between molecules or between molecules and ions. These forces are much weaker than bonding forces. The forces that exist among nonpolar molecules and noble gas atoms are only London dispersion forces. The attractions between molecules with dipole moments or polar molecules are dipole-dipole attractions. WebSince hydrogen bonding is stronger than LDF and dipole-dipole forces, we can say that the highest intermolecular force present in NH 3 is hydrogen bonding. Now I hope that you are feeling more confident about the factors that increase and decrease the strength of intermolecular forces!
