WebA Lewis base is a chemical compound that can donate a pair of electrons to a suitable electron-pair acceptor (Lewis acid) to form a Lewis adduct. Thus, the definition, chemical behaviour, and the applications of Lewis acids and bases are briefly discussed in this article. WebIn a complex ion, we have a central atom, often consisting of a transition metal cation, which acts as a Lewis acid, and several neutral molecules or ions surrounding them called ligands that act as Lewis bases. Complex ions form by sharing electron pairs to form coordinate covalent bonds.
