A student is given a mixture of propanone (boiling point 56 ∘C56\ ^\circ\text{C}56 ∘C) and water (boiling point 100 ∘C100\ ^\circ\text{C}100 ∘C).
Which combination of apparatus should the student use to separate these two liquids efficiently using fractional distillation?
A separating funnel and a conical flask
A round-bottom flask, a fractionating column, and a condenser
