Reactivity 3.3.1—A radical is a molecular entity that has an unpaired electron. Radicals are highly reactive. Identify and represent radicals, e.g. and .
NoneReactivity 3.3.2—Radicals are produced by homolytic fission, e.g. of halogens, in the presence of ultraviolet (UV) light or heat. Explain, including with equations, the homolytic fission of halogens, known as the initiation step in a chain reaction.
