Question
Which type of distillation is used when the boiling points of the liquids in a mixture are very close (difference less than 25-30°C)?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Fractional distillation uses a fractionating column to achieve multiple vaporization-condensation cycles, effectively separating liquids with close boiling points (e.g., methanol and ethanol, petroleum fractions).
Hint
Uses a fractionating column.
