WebJun 6, 2016 · The halogenation of toluene is possible by two mechanisms. In German, they are referred to by the shorthands KKK and SSS, where KKK stands for Katalysator, Kälte, Kern (catalyst, cold and core) while SSS is Sonne, Siedehitze, Seitenkette (sun, sizzling heat and side chain).. At low temperatures and in the presence of an activating … WebApr 7, 2024 · Mechanism of Free Radical Substitution Reaction. 1. Chain initiation- In the presence of heat or light, the chlorine molecule undergoes homolytic cleavage, releasing a chlorine free radical, which commences the reaction. As a result, the C-C and C-H bonds are easier to break. 2.
WebDuring 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 … WebRadical mechanisms are written in two different ways: (i) Each individual step is written without the use of arrows, depicting the order of events, ...
