A structured lesson including starter activity, AfL work tasks and lesson slides on free radical substitution reactions

By the end of this lesson KS5 students should be able to:

1.To know what a free radical is
2. To describe the reaction mechanism for the free-radical substitution of alkanes including initiation, propagation and termination
3. To analyse the limitations of radical substitution in synthesis by formation of a mixture of organic products
