Radical substitution chemistry

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: WebRadical Substitution Mechanism Unlike the large majority of reactions that you will see in your organic chemistry course, radical mechanisms require that fishhook curly arrowsthat represent the motion of a single electron are used. These can be a little more confusing and more difficult to master. We suggest you get to

WebMar 22, 2016 · Hence, For chlorination in alkanes, if you use S O X 2 C l X 2, It undergoes a free radical substitution reaction and will get the product. If we use S O C l X 2, it undergoes a nucleophilic substitution reaction. Here, this reaction mechanism is explained. So, You can see here that S O C l X 2 doesn't produce a chlorine free radical. WebThe free-radical substitution reaction consists of three steps: Initiation step. In the initiation step the Cl-Cl or Br-Br is broken by energy from the UV light; This produces two radicals in a homolytic fission reaction; The first step of the free-radical substitution reaction is the initiation step in which two free radicals are formed by sunlight
