Question

A mixture of liquids having almost the same boiling point cannot be separated by simple distillation?Why?​

Answer 1

Distillation:

Distillation is the process in which two or more liquids are separated on the basis of their boiling points.

Process:

Liquid mixture is heated. The liquid which is of low boiling point evaporates first and is condensed separately. This is followed by the liquid having more boiling point than the previous one and so on.

Reason:

A mixture of liquids having almost same boiling points cannot be separated. This is because both the liquids will evaporate at almost the same time when heated and thus, we will obtain the same liquid mixture again. No separation will occur.
