A Lewis acid ('''LA''') can accept a pair of Electron s and form a Coordinate Covalent Bond . The Lewis acid and Lewis Base theory, named after the American Chemist Gilbert Lewis , is one of several Acid-base Reaction Theories . Therefore the term '' Acid '', per se, is ambiguous; it should always be clarified as being a Lewis acid or a Brønsted-Lowry acid. An Electrophile or electron acceptor is a Lewis acid. A Lewis acid usually has a low-energy LUMO , which interacts with the HOMO of the Lewis base. Unlike a Brønsted-Lowry Acid , which always transfers a Hydrogen Ion (H+), a Lewis acid can be any electrophile (including H+). Although all Brønsted-Lowry acids are Lewis acids, in common usage the term ''Lewis acid'' is often reserved for those Lewis acids which are not Brønsted-Lowry acids. |
