Answer:
fractional distallation is used where the difference between the boiling point of substance is less than 25°C. if we use distillation in this case than the different substance get enough heat energy and they also get converted into vapour and hence we are not able to separare it . so in such cases fractional distillation use

Answer:
Fractional distillation is the process of separation of a mixture of two or more miscible liquids having very close boiling points (differing less than 25°C). Fractionating columns are used for distillation in this technique.
Importance:
a. It is useful in obtaining petroleum products from crude oil.
b. It is also useful in separating different components of air.
