Secondary free radical
WebIn chemistry, a radical, also known as a free radical, is an atom, molecule, or ion that has at least one unpaired valence electron. [1] [2] With some exceptions, these unpaired electrons make radicals highly chemically reactive. Many radicals spontaneously dimerize. Most organic radicals have short lifetimes. WebFree radicals are reaction intermediates formed due to the homolytic cleavage of a covalent bond containing carbon such that carbon gets an unpaired electron. In this process each atom takes away one of the two electrons forming a single covalent bond. It will produce two new species having an unpaired electron.
