WebbHere is the quick summary of radical reactions: Initiation = 1 neutral provides two radicals. Propagation = 1 neutral + 1 radical provides a different neutral and a different radical. Termination = 2 radicals providing one neutral. Hope this was helpful to you all, and as always, happy reacting. WebbDuring the propagation step the methane free radical reacts with a Cl-Cl molecule, forming CH3-Cl AND regenerating the Cl free radical, which can react with another methane to form a methane free radical. If you think about the initiation step only needs to occur once in theory. Then the propagation step can just keep going.
