Q. The method that can be used to separate a liquid from a mixture of miscible liquids with different boiling points is ___________ distillation.

Why fractional distillation is used to separate miscible liquids whose boiling points is less than 25K ?

Both simple distillation and fractional distillation can be used to separate two miscible liquids present in a mixture. If they differ in boiling points by more than $25^{\circ}$ $C$ , simple distillation is used. In case the difference is less than this temperature, then the process of fractional distillation can be employed. A fractionating column is used in the case of fractional distillation and is placed in the distillation flask. It can have a variety of shapes. No such column is needed in the case of simple distillation.
