  • Radical Substitution (for Cl)
    • Step 3
      • Termination
        • Two radicals combine to form a Cl molecule
        • Cl. + Cl. --> Cl2
          • .CH3 + .CH3 --> C2H6
          • .CH3 + .Cl --> CH3Cl
        • Removes radicals stopping reaction
    • Step 1
      • Initiation
      • Cl-Cl bond broken to form 2 radicals
        • HOMOLYTIC FISSON
      • Cl-Cl --> Cl. + Cl.
    • Step 2
      • Propagation
        • First stage
          • Methane reacts with chlorine radical
          • C-H bond broken by HOMOLYTIC FISSION
            • Forms methyl radical + HCl
          • CH4 + Cl. --> .CH3 + HCl
        • Second Stage
          • Methyl radical reacts with Cl molecule
          • Product = chloromethane + Chlorine radical
          • .CH3 + Cl2 --> CH3Cl + Cl.
        • Chain reaction
          • Rapid
