• A Lewis acid is a lone pair acceptor and a Lewis base is a lone pair donor. • When a Lewis base reacts with a Lewis acid a coordinate bond is formed. • A nucleophile is a Lewis base and an electrophile is a Lewis acid.
DEFINITIONS. Lewis acids and bases are defined in terms of electron pair transfers. A Lewis base is an electron pair donor, and a Lewis acid is an electron pair acceptor. An organic transformation (the creation of products from reactants) essentially results from a process of breaking bonds and forming new ones.

29 lip 2024 · Definition: Lewis Acids and Bases. A Lewis acid is any species (molecule or ion) that can accept a pair of electrons, and a Lewis base is any species (molecule or ion) that can donate a pair of electrons. A Lewis acid-base reaction occurs when a base donates a pair of electrons to an acid.
In 1923, G. N. Lewis proposed a generalized definition of acid-base behavior in which acids and bases are identified by their ability to accept or to donate a pair of electrons and form a coordinate covalent bond.
Examples of Lewis acids: BF3, AlCl3, SbF5, Na+, H+, S6+, etc. Examples of Lewis bases: F-, H2O, Me3N, C2H4, Xe, etc. Lewis Continued. A more general view also classifies compounds that can generate a species with an empty orbital as Lewis acids. Then we can include B2H6, Al2Cl6, HCl etc.
