Webelectrons. Whereas heterolytic bond cleavage leads to ion pairs, homolytic bond cleavage results in unpaired electrons – or free radicals. Some weak bonds have a tendency to fragment homolytically (e.g., peroxides halogens). Chemists use a slight variation of curved arrow notation to show the movement of single electrons. For Web23 nov. 2014 · Homolytic cleavage is the breaking of a covalent bond in such a way that each fragment gets one of the shared electrons. The word homolytic comes from the …
