With hydrogen fluoride, hydrogen bonding is an intermolecular bond that keeps the molecules together. Keep in mind this is different than the intramolecular forces like covalent or ionic bonds that keep atoms together to bond as molecules. Intermolecular forces keep the molecules attracted to each ...
The different stoichiometric patterns observed for the formation of hydrogen fluoride complexes by various amines, as well as the balance between formation of molecular complexes or ionic salts, may be related to the ability of the system to form extended networks of hydrogen bonds. The preparation ...

Several fluorine-containing ethanes (monofluoro, 1,1-difluoro, 1,1,1-trifluoro, 1,1,2-trifluoro, 1,1,2,2-tetrafluoro, and pentafluoro) and ethenes (1,1-difluoro and trifluoro) form hydrogen fluoride when irradiated with gamma rays in the gas phase at 25°C. Hydrogen fluoride is ...
Hydrogen fluoride is a significant HBD but a poor HBA. Oxygen is not always an HBD or HBA. Ammonia is a significant HBA but a poor HBD. There are many examples of H-bridges that do not contain these three elements. All examples of H-bridges should be shown in a way to provide ...
