Reactions of alkanes OCR AS Chemistry

This complete year 12 lesson on reactions of alkanes covers part of OCR sections 4.1.2 (Alkanes). Content covered includes reactivity of alkanes, combustion reactions and substitution by halogens including the radical substitution mechanism. The resource features a 38 slide animated PowerPoint along with a 13 page workbook. There is a starter activity and a plenary activity with timer. Exam tips and answers to the exercise are provided. Ideal for the classroom or blended learning, this resource could be used as an introduction to the topic, or for revision, extension or consolidation.
This lesson is part of a series covering the OCR AS Chemistry specification and relates to the following part of the specification:
