In the same year that Brønsted and Lowry published their theory, G. N. Lewis created an alternative theory of acid–base reactions. The Lewis theory is based on electronic structure . A Lewis base is a compound that can give an electron pair to a Lewis acid , a compound that can accept an electron pair.

Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
In chemistry, pyramidal inversion (also umbrella inversion) is a fluxional process in compounds with a pyramidal molecule, such as ammonia (NH 3) "turns inside out". [ 1 ] [ 2 ] It is a rapid oscillation of the atom and substituents, the molecule or ion passing through a planar transition state . [ 3 ]
