4
Q
Alkanes and halogen substitution reaction steps and conditions
A
Initiation
Propagation
Termination
In the presence of UV light
5
Q
Initiation
A
Energy from the UV light causes the Cl-Cl bond to break homolitically and firm to chlorine free radicals

A
Radical removes a hydrogen atom from methane producing hydrogen chloride and a methyl radical
Radical produces another radical
7
