Halogenation's Three steps
|
1. Initiation
2. Propagation 3. Termination |
|
|
Initiation
|
The halogen starts as a diatomic molecule which is homolytically cleaves by heat or UV light resulting in free radicals
|
|
|
Propagation
|
The halogen radical removes a hydrogen from the alkane resulting in an alkyl radical.
|
|
|
Termination
|
Either two radicals bond or a radical bonds to the wall of the container to end the chain reaction or propagation
|
|
|
Stability of radicals
|
3 > 2 > 1 > methyl
|
|
|
