What the lesson covers

What Are Structural Isomers?
IUPAC Naming: Branched Alkanes
The Isomers of C₅H₁₂
Position Isomers

How it is interactive

6 multiple-choice questions
2 true or false questions
1 fill-in-the-blank question
1 sorting and ordering task
1 sentence-writing task
1 drag-the-words sentence
1 reveal card

Feedback and what you get

Questions are marked automatically as pupils answer: a sound and a character reaction show straight away whether they are right, and correct answers earn points, with a results screen at the end. Sentence-writing tasks are for pupils' own answers and are not marked automatically.

Same atoms, different arrangement — and one set of rules to give every compound a clear name. This 20-slide interactive lesson on structural isomers takes pupils from first ideas to exam-style explanations, with 12 self-marking activities and nothing to prepare beforehand.

Teaching Isomerism and Naming Organic Compounds in GCSE extension and A-level Chemistry

Pupils define structural isomers, identify isomers from condensed formulae and name branched alkanes using IUPAC rules: longest chain, branch names and lowest position numbers. They work through the three isomers of C₅H₁₂, explain why branching lowers boiling point and name position isomers such as but-2-ene and propan-2-ol.
