Question

By which process we can get higher yields of gasoline in cracking?

(a) Electrolytic decomposition

(b) Thermal decomposition

(c) Nuclear energy

(d) Destructive distillation

The question was posed to me in an online interview.

Origin of the question is Cracking in section Fuels and Combustion of Engineering Chemistry II

Answer 1

The correct answer is (b) Thermal decomposition

The explanation: The process of cracking involves the thermal or catalytic decomposition of surplus heavier fractions, so as to obtain a higher yield of improved gasoline. It was noticed that cracked gasoline gives better engine performance.
