What is the main purpose of the fractionating column in fractional distillation?
To rapidly cool the vapors before they reach the condenser.
To facilitate the separation of liquids with close boiling points by increasing surface area.
To prevent the vapors from reaching the condenser.
To increase the rate of the distillation process.
Explanation
The fractionating column provides a large surface area for repeated vaporization and condensation, improving the separation of liquids with close boiling points.
