An acid-base reaction is the sharing of an electron pair with an acid by a base. These three simple definitions constitute the heart of what is now known as the Lewis concept of acids and bases. Experimentally and conceptually, they are an extension of the Brønsted definitions. In one br...
Acids and bases are an important part of organic chemistry. One of the most applicable theories is the Lewis acid/base motif that extends beyond the Brønsted-Lowry definition described in the previous section. Introduction The Brønsted-Lowry acid-base theory is still used extensively, but it ...

form a Lewis acid-base adduct. Here, the electron pair is transferred between the oppositely charged species to satisfy the octet. The Lewis acids and bases concept is further reiterated by the reaction between electron-deficient boron trifluorideand an electron-rich ammonia, as shown in Figure 1...

Lewis Acids and Bases:In the Lewis definition of acids and bases, an acid is defined as a substance capable of accepting a pair of nonbonding electrons. On the other hand, a base is defined as a substance that is capable of donating a pair of its nonbonding electrons. In other words,...
Lewis acid-base concept 酸碱电子理论 酸碱电子理论(the electronic theory of acid and alkali),也称广义酸碱理论、路易斯(lewis)酸碱理论,是1923年美国物理化学家吉尔伯特·牛顿·路易斯(Lewis G N)提出的一种酸碱理论
"A Lewis acid is an electron-pair acceptor,and Lewis base is an electron-pair donor". Or, in the language of frontier molecular orbital (FMO) theory the Lewis model becomes: "A Lewis acid interacts by its lowest unoccupied molecular orbital or LUMO, and a Lewis base interacts via its hig...
2.2.3Acid-base adsorption Gilbert N. Lewis, an American physical chemist, put out the Lewis acid-base hypothesis. According to the electronic theory of acids and bases, all molecules, ions, and groups of atoms that can accept electron pairs are referred to as acids, and all molecules, ions...
There are only acids, bases, and acid-base complexes in the theory of 1.Lewis acids and bases, and there is no concept of salt; 2., in the theory of acid-base electron, whether a substance belongs to the base, or whether it belongs to an acid, or a acid-base complex, should be...
