Short explanation
Explain that aqueous solutions of ethanol are produced when sugar solutions are fermented using yeast. This objective belongs to Alcohols within Reactions of alkenes and alcohols (chemistry only) for AQA GCSE Chemistry 8462. A strong answer should use ethanol 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.
