Solution

Simple distillation
Fractional distillation
Simple distillation is used to separate mixtures which are having boiling points with a gap of a minimum of 50 degrees. Fractional distillation is used in separating liquids having boiling points close to one another.
In simple distillation, the experimental setup is simple having two flasks and a condenser. In fractional distillation, the experimental setup is complex consisting of complex apparatus and a fractionating column.
Simple distillation is used in purification of seawater. Fractional distillation is used in the process of refining crude oil.
Simple distillation can be used in purification of seawater and fractional distillation can be used in crude oil refining.

Q. Question 33

Write the difference between simple distillation and fractional distillation.

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.

Fractional distillation is used in separation of crude oil instead

Of simple distillation, why?
