This KS4 resource is an introduction to alkanes and alkenes, their similarities and differences.

The PowerPoint begins with a starter activity, information slides introducing hydrocarbons and alkanes and then a summary. It then moves on to introduce alkenes and to compare them with alkenes, including the bromine test to identify alkenes. The final slides explore the reactions of alkenes.

There is a worksheet which students can fill in to summarise the structural and molecular formulae of the alkanes and alkenes. The answers are included.

Overall the resource is good. However there is a serious error on the alkenes answer sheet where the molecular formula for butene is incorrect.
