Answer
Fractional distillation
Explanation
Fractional distillation separates crude oil into fractions by heating it so that hydrocarbons evaporate and condense at different temperatures, creating groups with similar carbon numbers.
Common mistake
Misunderstanding Fractional Distillation
Students often think that fractional distillation separates crude oil into pure substances rather than fractions containing mixtures of hydrocarbons.
Clarify that fractional distillation separates crude oil into fractions, each containing a mixture of hydrocarbons with similar boiling points.
