3.4 Chlorination of Methane The Radical Chain

Since the ΔH for the chlorination of methane is negative the reaction is exothermic. Energetically this reaction is favorable. In order to better understand this reaction we need to look at the mechanism ( a detailed step by step look at the reaction showing how it occurs) by which the reaction occurs.
