What reaction mechanisms reveal
What reaction mechanisms reveal
Step-by-step process of how reactions actually happen
Homolytic fission
Homolytic fission
Bond breaks evenly; each atom gets one electron from the pair
Species with unpaired electrons
Species with unpaired electrons
Radicals
Heterolytic fission
Heterolytic fission
Bond breaks unevenly; one atom takes both electrons
Products of heterolytic fission
Products of heterolytic fission
Negative ion (anion) and positive ion (cation/carbocation)

Addition reaction
Addition reaction
Two molecules combine to form a single product
Substitution reaction
Substitution reaction
