WebWhich of the following is a chain propagation step in the free radical chlorination of methane? · CH3 + Cl · → CH3CI Cl2 2 Cl. CH4 + Cl HCI + · CH3 CH3 + CH4 → CH4 + CH3 Question Transcribed Image Text: Which of the following is a chain propagation step in the free radical chlorination of methane? WebAs described above, in the chlorination of alkanes by free radical substitution, one or more hydrogen atoms in an alkane is replaced by a chlorine free radical. UV light is used as a catalyst and hydrochloric acid is also given off. For example, the substitution of methane using chlorine produces chloromethane. The overall equation is as follows: WebCollision of the chlorine atom generated in the second propagation step with another molecule of methane forms a second molecule of HCl and a second methyl radical. The two propagation steps continue until the concentrations of Cl 2 and/or CH 4 are reduced to the point where the probability of a collision between two radicals becomes significant. redneck bbq north hills
