WebHydrogen bonding is a special type of intermolecular force that occurs between molecules that contain a hydrogen atom or a fluorine, nitrogen, or oxygen atom. Hydrogen bonds are just dipole-dipole interactions that are stronger than other dipole-dipole interactions. Web23 de sept. de 2024 · Hydrogen bonding is generally used to explain the high boiling point of water (100 ˚C). For many compounds which do not possess highly polarized bonds, boiling points parallel the molar mass of the compound. Methane, CH 4, has a molar mass of 16 and a boiling point of –164 ˚C. Water, with a molar mass of 18, has a boiling point …
