* Free radicals

- Addition to double and triple bonds-if the free radical formed is more stable than the free radical reacting then reaction is favouable
 - H-abstraction reaction - formation of trietyl radical

* Arrow pushing mechanism
 - Arrow starts from electron rich center
 - Arrow head pointing at an electron deficient center

* Substitution reaction is of two types

| Electrophilic | Nucleophilic |
| -------- | -------- |
| Aliphatic    | Aliphatic     |
| Aromatic    | Aromatic     |
