C10 - Organic reactions
(Set 1 only)
Independent Learning
Introduction
The reactions of organic molecules (molecules that contain carbon) play a vital role in the chemistry of life, as well as many industrial chemistry applications. In this unit, you learn about some of the reactions of different organic compounds, including alkenes, alcohols and carboxylic acids.
