How will you effect the separation of a mixture of acetone and methyl alcohol which are miscible with each other?
Or
Give a brief description of fractional distillation.

Fractional distillation: This process is generally used for those mixtures, where the difference in the boiling points of the two liquids is less than 15 K. Acetone boils at 330 K while methyl alcohol at 338 K, therefore, these two liquids are separated by the fractional distillation process. This is similar to the ordinary distillation method with the only exception that a fractionating column is introduced in between the distillation flask and the condenser.
The process of separation of the components of a liquid mixture at their respective boiling points in the form of vapours and the subsequent condensation of these vapours is called fractional distillation.

The fractionating columns used for the purpose are of different shapes as shown in the figure.
