Question

During fractional distillation of petroleum, different fractions are obtained. Their name, number of carbon atoms, temperature range at which it is obtained and their use are given. There is an error in one of the alternatives. In which alternative there is an error?

• A. Petrol, $C_5$ to $C_{10}$, $303$K to $393$K, fuel in vehicles
• B. Diesel, $C_{15}$ to $C_{18}$ $533$K to $613$K, fuel in vehicles and generators
• C. Neptha, $C_8$ to $C_{10}$ $393$K to $453$K, solvent in petrochemicals
• D. Lubricating oil, $C_8$ to $C_{12}$, $400$K, fuel in high speed vehicles

Answer 1

The correct option is D Lubricating oil, $C_8$ to $C_{12}$, $400$K, fuel in high speed vehicles

Lubricating oil, $C_8$ to $C_{12}$, $400$K, fuel in high speed vehicles. Lubricating oil, $C_{20}$ to $C_{30}$, above $613$K, is used as lubrication oil in machine and to prepare grease, vaseline, wax etc.
