acid: electron pair acceptor Base: electron pair donor
Lewis
Gilbert Newton Lewis described a base as a compound that donates an electron pair. This concept is known as the Lewis acid-base theory, which was proposed in 1923. Lewis also introduced the idea of electron pairs being shared in covalent bonds.
The Brønsted-Lowry theory defines acids as proton donors and bases as proton acceptors, focusing on the transfer of hydrogen ions (H⁺) in chemical reactions. In contrast, the Lewis theory broadens the definition of acids and bases by describing Lewis acids as electron pair acceptors and Lewis bases as electron pair donors, emphasizing electron interactions rather than just proton transfer. This distinction allows the Lewis theory to encompass a wider range of chemical reactions beyond those involving protons. Thus, while Brønsted-Lowry is more specific to proton transfer, Lewis theory addresses broader electron pair dynamics.
NO hydrogen ion need be involved.
Lewis theory, developed by Gilbert N. Lewis, is a conceptual framework in chemistry that describes how atoms bond together to form molecules. It emphasizes the role of electron pairs in chemical bonding, specifically through the sharing of electrons (covalent bonding) and the transfer of electrons (ionic bonding). The theory uses Lewis structures to visually represent molecules, showing valence electrons as dots and bonds as lines, which helps predict molecular geometry and reactivity. Overall, Lewis theory provides a foundational understanding of molecular structure and bonding interactions.
Gilbert Lewis followed by Linus Pauling who is credited with the quantum mechanical approach, called valence bond theory (distinguishing it from the more recent molecular orbital theory), which is based on Lewis's electron pair bonding theory now taught as Lewis "dot" diagrams.
