Other functional groups which also tend to form radicals when exposed to heat or light are chlorofluorocarbons, peroxides, and the halogenated amide N-bromosuccinimide (NBS).
WebA reactive intermediate with a single unpaired electron, formed by the homolytic cleavage of a covalent bond. The stability of radicals increases along the series from primary to … WebIn homolytic cleavage the movement of a single electron takes place instead of an electron pair. The organic reaction which proceed through homolytic bond cleavage are called ionic reactions or polar reactions. Homolytic cleavage results in the formation of neutral species which contains an unpaired electrons. None of the above
