Essential Chemistry for IGCSE - Organic Chemistry And Petrochemicals (Section 1 - No. 6)
Which of the following statements correctly describe the process of fractional distillation?
Crude oil is heated to vaporize the hydrocarbons.
Hydrocarbons with similar boiling points are collected together.
The fractions are separated based on their densities.
The temperature in the fractionating column increases from top to bottom.
Explanation
Crude oil is heated to vaporize it, and fractions with similar boiling points are collected together. The fractions are separated according to their boiling points not their densities. The temperature is higher at the bottom and lower at the top.
