In
chemistry,
homolysis (from Greek ὅμοιος, homoios, "equal," and λύσις, lusis, "loosening") or
homolytic fission is
chemical bond dissociation of a
molecule by a process where each of the fragments retains one of the originally bonded electrons. During homolytic fission of a neutral molecule with an even number of electrons, two
free radicals will be generated. That is, the two
electrons involved in the original bond are distributed between the two fragment species.
