Free radical chlorination mechanism
WebThe mechanism for this reaction takes place in three steps. 1. Initiation Step: The Cl-Cl bond of elemental chlorine undergoes hemolysis when irradiated with UV light, and this process yields two chlorine atoms, also called chlorine radicals. 2. Propagation Step: A chlorine radical abstracts a hydrogen atom from methane to produce the methyl ... WebRadical Chlorination - lab report . lab report .
