Radical
What is Radical?
A radical (free radical) is a highly reactive chemical species with one or more unpaired electrons, generated by the homolytic cleavage of a covalent bond. Radicals play key roles in chain reaction mechanisms (such as halogenation of alkanes, combustion, and polymerization), atmospheric chemistry (ozone depletion, smog formation), and biological processes (oxidative stress, aging). They are typically short-lived due to their high reactivity and can be detected by electron spin resonance (ESR) spectroscopy.
