Question

Name any two fractions obtained during fractional distillation of petroleum along with the temperatures at which these are collected. Write one use of each fraction.

Answer 1

Fractional distillation: It is a process through which the components of crude oil are separated into usable products. The fractional distillation of petroleum is called refining, and it depends on the fact that each compound of petroleum has a different boiling temperature.

Explanation: The two fractions obtained during fractional distillation of petroleum are

1. Petrol is obtained at $40°-170°\mathrm{C}$
2. Diesel is obtained at $250°-350°\mathrm{C}$

Applications:

1. Petrol is used as fuel in cars.
2. Diesel is fuel for railway engines and diesel power plants.
