CoachA reactive intermediate is a species formed in one step of a mechanism and consumed in a later one, too reactive to accumulate (Chapter 9). A carbocation has a carbon with three bonds and a positive charge (six valence electrons); a carbanion a carbon with three bonds, a lone pair and a negative charge; a radical an atom with an unpaired electron.
