Hydrocarbons and Homologous Series — Interactive Lesson (Ages 14–16)

Why can carbon form millions of compounds when most elements form only a handful? This 22-slide interactive lesson on homologous series takes pupils from first ideas to exam-style explanations, with 13 self-marking activities and nothing to prepare beforehand.

Teaching Hydrocarbons and Homologous Series in GCSE Chemistry

Pupils start with the unique nature of carbon — four covalent bonds and catenation — then learn to spot a hydrocarbon from its formula. The lesson builds the idea of a homologous series step by step: general formula, functional group, the CH₂ difference between members and the gradual trend in boiling point. Naming prefixes from meth- to pent- and a first look at alkanes, alkenes, alcohols and carboxylic acids prepare pupils for every organic topic that follows.

What Pupils Will Learn

• Explain why carbon can form so many different compounds.
• Identify a hydrocarbon from its formula.
• Describe the features of a homologous series.
• Use the prefixes meth-, eth-, prop-, but- and pent- to name compounds.
• Describe how properties change as the carbon chain gets longer.

What’s Included
