In the same sequence, which product comes after gasoline?

• A. Refinery gases
• B. Kerosene
• C. Diesel
• D. Bitumen

Answer: (B)

Fractional distillation of crude oil separates components by boiling point, with lighter fractions rising to the top and condensing there, and heavier ones collecting lower down. The sequence from light to heavy is refinery gases, gasoline, kerosene, diesel, lubricating oils, and then bitumen. Gasoline boils at a lower temperature range than kerosene, so after gasoline the next fraction that vaporizes and then condenses further down the column is kerosene. That’s why kerosene comes after gasoline in the distillation sequence. The heavier diesel and eventually bitumen sit further down because they boil at even higher temperatures.
