WebTermination. Termination removes the remaining free radicals. This can occur in multiple different ways, but in each case, two radicals react together to form a stable compound. For example: Two chlorine radicals react together to form a chlorine molecule: \(Cl\cdot \space +\space Cl\cdot \rightarrow Cl_2\) Can this chain reaction go on forever? No. Let’s think about two limiting cases. If the concentration of Cl2 is low relative to CH4 (in other words, Cl2 is our limiting reagent) then the rate of Propagation Step #2 will slow down as its concentration decreases. Without any Cl2 to react with, our •CH3 radicals can just combine … See more You may recall seeing this reaction in a previous post – it’s the free radical chlorination of methane with Cl2. It’s a substitution on … See more It’s here where it’s easy to make a little mistake. Seeing that there’s two chlorine radicals formed in the initiation step, it would seem natural to … See more Let’s put all of these steps together so we can clearly see the initiation, propagation, and termination steps. See more In fact, we can do the proper “propagation” step this way: Take the methyl radical, and it reacts with the Cl2still present. This gives us CH3Cl and the chlorine radical. Note that there has … See more
