Hydrogen Bonds
Hydrogen bonds are a type of intermolecular or intramolecular interaction that occurs between a hydrogen atom bonded to an electronegative atom (typically nitrogen, oxygen, or fluorine) and another electronegative atom. Hydrogen bonds are responsible for various properties and behaviors of molecules, including the unique properties of water, the stability of secondary protein structures, and the…
