Overview of addition, elimination, substitution and rearrangement reactions
108.4 Substitution reactions
This involves the exchange of one group for another.
AB + CD → AC + BD
Common reaction types include
- radical reactions and
- nucleophilic substitutions
- SN1, Unimolecular nucleophilic substitution
- SN2, Bimolecular nucleophilic substitution
108.5 Rearrangement reactions
A molecule shifts or otherwise rearranges to form a different molecule.
A → B
This typically happens when one molecule changes into an isomer of itself.
