REACTIVE INTERMEDIATES
The following transient species are detected as reactive intermediates between reactants & final products.      Generally unstable.
Carbocations
6 electrons, electron deficient,
highly reactive
Radicals (free radicals)
7 electrons, electron deficient,
highly reactive
Carbanions
8 electrons, carbon has low EA and
so the lone pair is reactive.
