Lewis acid–base interactions play an important role in understanding chemical bonds, reactions and equilibrium; yet, this concept is often inadequate for solid state chemistry. Indeed, in a redox reaction, single-electron transfers are also ...

Hypervalent molecule

A hypervalent molecule (the phenomenon is sometimes colloquially known as expanded octet) is a molecule that contains one or more main group elements formally bearing more than eight electrons in their valence shells. Phosphorus pentachloride (PCl5), sulfur hexafluoride (SF6), chlorine trifluoride (ClF3), and the triiodide (I3−) ion are examples of hypervalent molecules.
