  • Free radical substitution reactions in alkanes and alkyl groups. Free radical addition during the polymerization of ethene and the reaction between HBr and alkenes in the presence of organic peroxides.

    • Bromination of Methane
      This page gives you the facts and a simple, uncluttered mechanism for the free radical substitution reaction between methane and bromine. This reaction between methane and bromine happens in the presence of ultraviolet light - typically sunlight. This is a good example of a photochemical reaction - a reaction brought about by light.
    • Chlorination of Methane
      This page gives you the facts and a simple, uncluttered mechanism for the free radical substitution reaction between methane and chlorine.
    • Methylbenzene and Chlorine
      This page gives you the facts and a simple, uncluttered mechanism for the free radical substitution reaction between methylbenzene (previously known as toluene) and chlorine.
    • What is Free Radical Substitution?
      Substitution reactions These are reactions in which one atom in a molecule is replaced by another atom or group of atoms. Free radical substitution often involves breaking a carbon-hydrogen bond in alkanes
