Covalent bondsDiborane or B2H6 forms covalent bonds that are also known as three centres and two-electron bonds123. In the diborane molecule, two types of H atoms are present, which are the hydrogen terminal atoms that form covalent bonds with B that are normally two centres and two-electron bonds1. The two electrons (corresponding to one bond) in a B−H−B bonding molecular orbital are spread out across three internuclear spaces2. In diborane, there are two such 3c-2e bonds: two H atoms bridge the two B atoms, leaving two additional H atoms in ordinary B−H bonds on each B2.Learn more:✕This summary was generated using AI based on multiple online sources.
