Question
Liquid hydrocarbons can be converted to a mixture of gaseous hydrocarbons by
-
oxidation
-
cracking
-
distillation under reduced pressure
-
hydrolysis
Solution
B.
cracking
Lower hydrocarbon exists in a gaseous 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.
