Web12 nov. 2024 · Accordingly, a Lewis acid is a substance that accepts an electron pair from a base while a Lewis base is a substance that donates an electron pair to an acid. Lewis acids are involved in enzyme-catalyzed processes as cofactors. Metal cations such as Mg 2+, Mn 2+, Zn 2+, and iron–sulfur clusters are Lewis acids. Weba base is described as being a H + ion or proton acceptor. To take a simple example of HCl reacting with NaOH. The HCl can be described as a proton donor and the NaOH can be described as a proton acceptor. Lewis Acids and bases The Lewis approach to describing acids and bases revolves around pairs of electrons to form covalent bonds.
