# During fractional distillation of petroleum, different fractions are obtained. Its name, number of atoms of carbon, the temperature range at which it is obtained and its use are given. There is an error in one of the alternatives. In which alternative there is an error?(a)Petrol, ${{C}_{5}}\text{ }to\text{ }{{C}_{10}},\text{ }303k\text{ }to\text{ }393K,$fuel in vehicles(b)Diesel, ${{C}_{15}}\text{ }to\text{ }{{C}_{18}},\text{ }533k\text{ }to\text{ }613K,$fuel in vehicles and generators(c)Naphtha, ${{C}_{8}}\text{ }to\text{ }{{C}_{10}},\text{ }393k\text{ }to\text{ }453K,$solvent in petrochemicals(d)Lubricating oil, ${{C}_{8}}\text{ }to\text{ }{{C}_{12}},\text{ }400K,$fuel in high speed vehicles

Hint: A method of distillation that requires the separation of miscible liquids is fractional distillation. Repeated distillations and condensations are involved in the process, and the mixture is typically divided into component sections.

Lubricating oil, ${{C}_{16}}\text{ }\text{ }to\text{ }{{C}_{20}}\text{ }\text{ }above\text{ }613K$ is used in machine lubrication oil and for the preparation of grease, vaseline etc.
Option (d) lubricating oil,${{C}_{8}}\text{ }\text{ }to\text{ }{{C}_{12}}\text{ }~400~K~$fuel in high speed vehicles is the right answer.
Note: In general, the component parts have boiling points which differ under one atmosphere pressure from each other by less than $25~{}^\circ ~C~\left( 45~{}^\circ ~F \right).$Usually a simple distillation is used when the difference in boiling points is greater than $25~{}^\circ ~C.$
