Alcohols and homologous series
Alcohols and homologous series
An alcohol is a member of a homologous series containing the functional group −OH-\text{OH}−OH. The −OH-\text{OH}−OH group is covalently bonded within the molecule, so it is not the hydroxide ion found in an alkali.
Step-by-step lessons on Edexcel GCSE Chemistry 10.4.1 Alcohols and the -OH functional group. Each one builds up to exam-style questions. Nail the core quantitative topics — moles, balancing equations and calculations — early on, since they underpin higher-tier questions across every paper and topic.
