Chlorination steps

Initiation: The halogen (cl-cl) bond is broken by homolytic fission forming two radicals CL* + CL* Propagation: 1. CH4 + Cl* ---> CH3 * + HCL 2.CH3* + CL2 ----> CH3Cl + CL* Termination: The cancellations of radicals for the initiation eq 1. CL* + CL* = CL2 2.CH3* + CH3*= C2H6 3.CH3* + CL* =CH3CL
