After kerosene in the sequence, which product is collected?

After kerosene in the sequence, which product is collected?

• A. Gasoline
• B. Diesel
• C. Fuel oil
• D. Bitumen

Answer: (B)

This question tests fractional distillation of crude oil into fractions by boiling points. In a distillation column, lighter fractions with lower boiling points rise higher and condense earlier, while heavier fractions with higher boiling points drip down and condense later. Gasoline boils at a relatively low range, so it’s collected near the top. Kerosene has a higher boiling point than gasoline, so it condenses further down the column. The next fraction to condense after kerosene is diesel, which has an even higher boiling point. Heavier products like fuel oil and bitumen come out even later or remain at the bottom, while gasoline would have come earlier. So the product collected after kerosene is diesel.
