Question

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

• A. Petrol, $C_{5}to{C}_{10}$, 303K to 393K, fuel in vehicles.
• B. diesel, $C_{15}to{C}_{18}$, 533K to 613K, fuel in vehicles and generators.
• C. Neptha, $C_{8}to{C}_{10}$, 393K to 453K, solvent in petro chemicals.
• D. lubricating oil, $C_{8}to{C}_{12}$, 400K, fuel in high speed vehicles.

Answer 1

Answer: (D)

lubricating oil, $C_{8}to{C}_{12}$, 400K, fuel in high speed vehicles.

Lubricating oil,$C_{16}$ to $C_{20}$ above 613K is used as lubrication oil in machine and to prepare grease,vaseline etc.

Therefore,lubricating oil $C_8$ to $C_{12}$,400K fuel in high speed vehicles is the correct answer.
