The technique ‘fractional distillation’ is based on the difference in the boiling points of the constituents of a mixture.
The process of ‘fractional distillation is used for separating the miscible components of a liquid mixture. The separation is possible due to the difference in boiling points of different components present in the mixture.
Example: It is used to separate crude oil “petroleum” into useful fractions such as kerosene, petrol, or diesel, etc.
Hence, the given statement is true.
