WebIn modern chemistry, electron donors are often referred to as nucleophiles, while acceptors are electrophiles. Proton-Transfer Reactions Involve Electron-Pair Transfer Just as any Arrhenius acid is also a Brønsted acid, any Brønsted acid is also a Lewis acid, so the various acid-base concepts are all "upward compatible". WebA molecule being oxidized is acting as an electron donor, while the molecule being reduced is acting as an electron acceptor. Since electrons represent energy, a substance with many electrons to donate can be thought of as energy-rich. Conjugate Redox Pair Electrons do not exist freely in solution, they must be coupled with atoms or molecules. WebPossible electron acceptors include the inorganic constituents oxygen, nitrate, manganese (IV), iron (III), sulfate, and carbon dioxide, as well as highly chlorinated VOCs such as PCE, TCE, and TCA. VC and dichlorinated ethenes and ethanes also may act as electron acceptors under strongly reducing redox conditions. swedish agro machinery skurup
