Question

What is Fractional distillation?

Answer 1

Fractional distillation:

$\bullet$ It is used when the boiling points of chemicals in a mixture are close to each-other.

Note: Usually within 77°F

$\bullet$ Fractionating columns used to separate the mixtures.

Example:

It is used in the separation of:

$\implies$ Crude oil into useful fractions

Answer 2

Heya.....

Fractional Distillation :-

It is called fractional distillation because it distribute the liquids into the fractions and separate out from the mixture....

The method to separate the liquids of a mixture having it's different boiling point and chemical consistency is known as fractional distillation...

Ex ___

Water and Petrol mixture.... In this water has low boiling point hence in this process water will soon vaporize and seperate our from petrol...

Thank you
