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 1

The Correct Option is B

To solve this question, we need to understand the process by which liquid hydrocarbons are converted into a mixture of gaseous hydrocarbons.

1. Understanding Liquid and Gaseous Hydrocarbons:
   • Hydrocarbons are organic compounds consisting entirely of hydrogen and carbon.
   • Liquid hydrocarbons include petroleum and crude oil components, while gaseous hydrocarbons include natural gas components like methane, ethane, etc.
2. The Process of Cracking:
   • Cracking is a process widely used in the petrochemical industry.
   • It involves breaking down large, complex molecules of liquid hydrocarbons into simpler, smaller gaseous hydrocarbons.
   • This is typically done with heat (thermal cracking) or catalysts (catalytic cracking).
3. Evaluating the Options:
   • Oxidation: This process involves the reaction of hydrocarbons with oxygen to form oxides, not converting liquids to gases.
   • Cracking: The correct process for converting liquid hydrocarbons to gaseous hydrocarbons. This involves breaking down larger molecules.
   • Distillation under reduced pressure: This is a separation process, often used to purify or separate components, not converting physical states.
   • Hydrolysis: Involves the chemical breakdown of compounds due to reaction with water, which is not applicable here.
4. Conclusion: Among the given options, cracking is the correct method to convert liquid hydrocarbons into gaseous hydrocarbons.
