Reaction mechanisms involving these substances are drawn using fish-hook arrows.
The geometries of one type of these substances include planar, rigid pyramidal, and rapidly inverting pyramidal. Moses Gomberg discovered one of these substances that contains three phenyl groups. Reactions involving polymers and these substances have initiation, propagation, and termination steps. Reaction mechanisms involving these substances are drawn using fish-hook arrows. Homolytic cleavage can produce these substances, as can the photo-dissociation of chloro-fluoro-carbons. Cells that can be damaged by these substances are protected by anti-oxidants. For 10 points, name these reactive substances that have an unpaired electron.
