22.6: Hydrogen: A Unique Element

An example of this kind of interaction is the hydrogen bonding network found in water (Figure (PageIndex{2})). Hydrogen can also form a three-center bond (or electron-deficient bond), in which a hydride bridges two electropositive atoms. Compounds that contain hydrogen bonded to boron and similar elements often have this type of bonding.
