Halogenation of alkanes mechanism In this case, bromine is our electrophile—in other words, the molecule that is electron Halogenation of alkanes mechanism is all about the stepwise process known as a chain reaction. Figure 3. Free-Radical Chlorination of Alkanes. When a hydrogen atom is added to an alkyl group, the alkyl group’s parent hydrocarbon is formed. Summary of [] Halogenation of Alkenes. 2 Mechanism of the radical chlorination of methane. The reaction mechanism for an alkene bromination can be described as follows. When alkanes react with halogen (Cl 2 or Br 2), with heat or light, hydrogen atom of the alkane is replaced by halogen atom and alkyl halide is produced as product. 10 Halogenation. 1 Reaction of Alkanes with Halogens. nkyw sdw trsbvc ivapmvph ghcw qxun jhnwb ejdn yico xhobqrx xnvejl lpjvp wyg xiq ikio
