Chemistry Question on Hydrocarbons
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
Explanation
Solution
Lower hydrocarbons exist in 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.
