radical halogenation of alkanes to make alkyl halides

Описание к видео radical halogenation of alkanes to make alkyl halides

Alkanes can be readily halogenated with Cl2 and light. In the initiation step, the Cl-Cl bond goes through homolytic cleavage to form two Cl radicals. In the first propagation step, a Cl radical removes a hydrogen atom from the alkane to make a new carbon radical. In the second propagation step, the carbon radical reacts with Cl2 to form an alkyl chloride and Cl radical. The net reaction based on the propagation steps is...
CH4 + Cl2 (starting materials) --- CH3Cl + HCl (products)
Termination involves the reaction of any two radicals in the reaction medium.
