路易斯酸碱概念是路易斯(G.N.lewis)于1923年提出,到了1938年才开始得到广泛传播和应用。他认为,酸是在反应过程中接受电子对的任何分子或离子,称为电子对的接受体,简称受体;碱是在反应过程中给出电子对的任何分子或离子,称为电子对的给予体,简称给体或授体,按照这种观点,酸碱反应是电子对的授受反应。这种概念着眼点是电子对的接受,因而路易酸碱范围很大,包括了所有的Br(o|¨)nstedlowry质子酸碱、Lux-Flood氧离子酸碱和溶剂体系酸碱,并且还补充了许多新的酸碱。参加除氧化还还原反应和自由基反应以外的几乎所有反应的物质都属于路易斯
The Lewis acid-base concept was proposed by G.N. Lewis in 1923 and did not begin to be widely disseminated and applied until 1938. In his opinion, the acid is any molecule or ion that accepts an electron pair during the reaction, called the acceptor of the electron pair, referred to as the acceptor. The alkali is any molecule or ion that gives the electron pair during the reaction, called the electron pair The donor, referred to as donor or donor, according to this view, the acid-base reaction is the electron transfer reaction. This concept focuses on the acceptance of the electron pair and therefore has a wide range of Lewis acids and bases, including all Br (o | ¨) nstedlowry Protonates, Lux-Floods and Solvents, Acid-Base, and also complements A lot of new acid and alkali. Substances that participate in almost all reactions other than the oxidation-reduction and radical reactions belong to Lewis
