A Lewis acid (named for the American physical chemist Gilbert N. Lewis) is a chemical species that contains an empty orbital which is capable of accepting an electron pair from a Lewis base to form a Lewis adduct.
A Lewis base is a chemical compound that can donate a pair of electrons to a suitable electron-pair acceptor (Lewis acid) to form a Lewis adduct. Thus, the definition, chemical behaviour, and the applications of Lewis acids and bases are briefly discussed in this article.
30 Jan 2023 · Acids and bases are an important part of chemistry. One of the most applicable theories is the Lewis acid/base motif that extends the definition of an acid and base beyond H + and OH - ions as described by Br ø nsted -Lowry acids and bases.
The Brønsted–Lowry concept of acids and bases defines a base as any species that can accept a proton, and an acid as any substance that can donate a proton. Lewis proposed an alternative definition that focuses on pairs of electrons instead. According to Lewis:
27 Mac 2022 · Lewis acid and base theory views the electron as the active species in an acid-base reaction. A Lewis acid is an electron pair acceptor, while a Lewis base is an electron pair donor.
13 Nov 2022 · Here are several more examples of Lewis acid-base reactions that cannot be accommodated within the Brønsted or Arrhenius models. Identify the Lewis acid and Lewis base in each reaction.
In the Lewis theory of acid-base reactions, bases donate pairs of electrons and acids accept pairs of electrons. A Lewis acid is therefore any substance, such as the H + ion, that can accept a pair of nonbonding electrons. In other words, a Lewis acid is an electron-pair acceptor.
