Abstract

A free radical is any chemical species (capable of independent existence) possessing one or more unpaired electrons, an unpaired electron being one that is alone in an orbital. Radicals (often denoted by the insertion of the radical dot (ㆍ) to indicate that one or more unpaired electrons is present) are generally less stable than non-radicals, although their reactivities vary.
