Previous Year NEET Question- Hydrocarbons L-3

Question: Liquid hydrocarbons can be converted to a mixture of gaseous hydrocarbons by#

A) oxidation

B) cracking

C) distillation under reduced pressure

D) hydrolysis

Answer: cracking#

Sol:#

Key Idea Lower hydrocarbons exist in goseous state while higher ones are in liquid state or solid state. On cracking or pyrolysis, the hydrocarbon with higher molecular mass gives a mixture of hydrocarbons having lower molecular mass. Hence, we can say that by cracking a liquid hydrocarbon can be converted into a mixture of gaseous hydrocarbons.
