Pupils use the general formula CₙH₂ₙ₊₂ to write formulae, explain why alkanes are saturated and describe how boiling point, viscosity and flammability change with chain length.

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.

From the cooking gas in a Lagos kitchen to the natural gas heating a UK home, alkanes power everyday life. This 22-slide interactive lesson on alkanes takes pupils from first ideas to exam-style explanations, with 13 self-marking activities and nothing to prepare beforehand.
Pupils use the general formula CₙH₂ₙ₊₂ to write formulae, explain why alkanes are saturated and describe how boiling point, viscosity and flammability change with chain length. They balance equations for complete combustion and explore the real dangers of incomplete combustion, including carbon monoxide from charcoal stoves and generators. An extension slide introduces substitution with chlorine in UV light for SSCE and A-level learners.
Supports the organic chemistry content of UK GCSE Chemistry (AQA, Edexcel and OCR) and the Nigerian Senior Secondary Chemistry curriculum (SS2–SS3), including WAEC and NECO exam preparation.
