WebIn chemistry, an electron donor is a chemical entity that donates electrons to another compound. It is a reducing agent that, by virtue of its donating electrons, is itself oxidized in the process. Typical reducing agents undergo permanent chemical alteration through covalent or ionic reaction chemistry. WebIn other words, a Lewis acid is an electron-pair acceptor. A Lewis base is any substance, such as the OH-ion, that can donate a pair of nonbonding electrons. A Lewis base is …
