Reaction mechanisms

Describe the difference between homolytic and heterolytic bond fission and recognise examples;

Recall the formation, nature and reactivity of radicals and explain the mechanism of a radical chain reaction involving initiation, propagation and termination;

Use a radical mechanism as a model to explain the reaction of alkanes with halogens (a radical chain reaction in the presence of UV radiation to form halogenoalkanes);
