WebGilbert N. Lewis put forward his definitions of acids and bases in the year 1923. According to this definition, an acid is an electron pair acceptor and a base is an electron pair donor. Therefore, a Lewis acid can be defined as a chemical entity that can accept a pair of electrons from a Lewis base to form a coordinate covalent bond with it. WebNow universally known as the Lewis acid-base definitions, these concepts define an acid as an electron-pair acceptor and a base as an electron-pair donor. First proposed, almost as a passing thought, in his 1923 monograph on chemical bonding, discussions of Lewis acids and bases are now found in most introductory chemistry textbooks. underwater basket weaving college https://pittsburgh-massage.com
