WebApr 20, 2024 · One of the oldest redox system for the generation of free radicals is Fenton’s reagent, (Fe2+/ H2O2):3,4 Fe2++ HOOH →HO•+ HO-+ Fe3+ In this reaction, precisely one electron is transferred from the iron (II) ion to the peroxide, triggering its dissociation and the formation of an iron (III) ion. WebA free radical is an atom, molecule, or compound that is highly unstable because of its atomic or molecular structure (i.e., the distribution of electrons within the molecule). As a result, free radicals are very reactive as they attempt to pair up with other molecules, atoms, or even individual electrons to create a stable compound.
