Short explanation

Explain that alkenes are unsaturated because they contain two fewer hydrogen atoms than the alkane with the same number of carbon atoms. This objective belongs to Structure and formulae of alkenes within Reactions of alkenes and alcohols (chemistry only) for AQA GCSE Chemistry 8462. A strong answer should use alkene accurately, explain the chemistry behind the statement, and connect the idea back to the exact command in the objective. When revising, separate this point from neighbouring Chemistry ideas by naming the relevant particle, substance, process, calculation, observation, or structure before giving the final conclusion.
