"WebIn a symmetrical rupture, each atom in the original covalent bond receives one electron. This type of rupture generates free radicals and is referred to as homolytic cleavage. In reactions, it generates free‐radical mechanisms. Asymmetrical breaking of a single covalent bond leads to ion formation and is referred to as heterolytic cleavage. " - Cleavage and covalent bonds
