🎯 Exam Focus: Alcohols
very-high Fermentation equation (2 marks): Must include glucose → ethanol + carbon dioxide. Don't forget the CO₂!
very-high Compare fermentation vs hydration (4 marks): Environmental impact, raw materials, speed, purity — must compare, not just describe one method.
high Functional group questions (1 mark): "-OH" — must include the dash showing it is attached to the carbon chain.
medium Carbon neutrality (2 marks): Bioethanol is approximately carbon neutral because the CO₂ released was recently absorbed by the plant crops used to make the sugar.
