    • A. Ethane
    • B. Methane
    • C. Propane
    • D. Butane

  3. 3. As you move up a fractionating column during the distillation of petroleum, what happens to the boiling point of the fractions collected?

    • A. It increases
    • B. It decreases
    • C. It stays the same
    • D. It fluctuates randomly

  4. 4. Which fraction of petroleum is used as fuel for diesel engines?

    • A. Refinery gas
    • B. Gasoline/petrol
    • C. Diesel oil/gas oil
    • D. Bitumen

  5. 5. A company is choosing between gasoline and fuel oil to power a small car engine that needs to ignite easily and burn quickly. Using your knowledge of fractional distillation trends, explain which is the better choice and why.

    • A. Fuel oil, because it has a longer chain length and ignites more easily
    • B. Gasoline, because it has a shorter chain length, is more volatile and has a lower boiling point, so it ignites more readily
    • C. Fuel oil, because it is collected higher up the fractionating column
    • D. Gasoline, because it has the highest viscosity and burns most slowly
