  3. 3. Ethanol is left in an open flask in air for several days. What is it most likely oxidised into?

    • A. Ethene
    • B. Ethanoic acid
    • C. Methanol
    • D. Carbon dioxide only

    • A. Filtration
    • B. Fractional distillation
    • C. Chromatography
    • D. Crystallisation

  5. 5. A student is told propan-1-ol reacts the same way as ethanol when oxidised. Which statement correctly explains why, and predicts the product?

    • A. Because both are hydrocarbons, propan-1-ol oxidises to propene
    • B. Because both share the –OH functional group, propan-1-ol oxidises to propanoic acid
    • C. Because both share the –COOH functional group, propan-1-ol oxidises to propanoic acid
    • D. Because alcohols cannot be oxidised, no reaction occurs
