Radical chemistry is a subfield of chemistry that studies chemical reactions involving free radicals, which are highly reactive species with unpaired electrons. These radicals can participate in a wide range of chemical reactions, including oxidation, reduction, and polymerization reactions. The study of radical chemistry is important in fields such as organic chemistry, biochemistry, and environmental chemistry, as radicals play key roles in many natural and synthetic processes. The understanding of radical chemistry can lead to the development of new and efficient methods for synthesis and the design of better materials with unique properties.
