Teacher and Student PP that reviews the reaction types and mechanisms of reactions studied over the two years of A Level Chemistry. The resource reviews such key terms as: electrophile, nucleophile, free radical, homolytic bond fission, heterophilic bond fission, carbocation. The following mechanisms are described and explained: free radical substitution nucleophilic substitution electrophilic substitution electrophilic addition nucleophilic addition nucleophilic addition-elimination elimination (haloalkanes with ethanoic hydroxide and alcohols with acid catalyst to form alkenes).

This resource is for Combined science and GCSE Chemistry. It is a PP* intended for a revision lesson on Chemical Analysis but not only; the content can be extracted for teaching lessons on Chemical Analysis (e.g., for starters, plenaries, homework or summary of main concepts for notes for students) or for catching up when students miss a lesson. The first few slides contain different types of questions (& answers) -(matching up, application questions, past exam questions and challenge questions) that will allow to assess students’ knowledge up to Grade 9 and above.

Teachers can select questions suitable for students in their class. The second part of the PP contains slides that review the key concepts for Chemical Analysis in the GCSE Chemistry 2015 specification. Again, the review is suitable for up to Grade 9.
