- D. As a beverage in alcoholic drinks
4. Ethanol can be produced by two different methods. Which statement correctly compares fermentation and hydration of ethene?
- A. Fermentation uses renewable resources; hydration requires an acidic catalyst and steam at high pressure
- B. Fermentation produces very pure ethanol; hydration produces ethanol contaminated with water
- C. Fermentation requires a phosphoric acid catalyst; hydration uses yeast and anaerobic conditions
