Recognising the reaction
Recognising the reaction
Alkanes have only carbon-to-carbon single bonds, alkenes contain a C=C\text{C}=\text{C}C=C double bond, and alcohols contain an −OH-\text{OH}−OH group. The functional group determines which reactions a compound undergoes.
Step-by-step lessons on OCR GCSE Chemistry 6.2.4 Reactions of alkanes, alkenes and alcohols. 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.
