In the sequence of products produced by fractional distillation, which comes immediately after refinery gases?

Explanation:
The main idea is that fractional distillation sorts crude oil by boiling points. In the distillation column, the lightest vapors rise to the top and condense first as refinery gases. The next lightest liquid fraction, which condenses lower in the column, is gasoline (petrol). Heavier fractions with higher boiling points—kerosene, then diesel, and finally bitumen—condense further down. So after refinery gases comes gasoline, the lightest liquid fraction used as fuel for cars.
