Question

Natural gas is mostly:

1. A. Oxygen
2. B. Hydrogen
3. C. Ammonia
4. D. Methane (Correct answer)

Correct Answer

Option D — Methane

Detailed Solution & Explanation

The correct answer is Methane.

Key Points

• Natural gas is mostly methane (CH₄), typically making up 70-90% of it.
• Smaller amounts of ethane, propane and butane are also present.
• Oxygen, hydrogen and ammonia are not principal constituents.

Additional Information

• CNG (Compressed Natural Gas) is largely methane and is used as a cleaner vehicle fuel; LPG by contrast is mainly butane and propane.
• Methane is a potent greenhouse gas — far stronger than CO₂ per molecule — and is also produced by paddy fields, livestock and landfills.
• Biogas, produced by anaerobic decomposition of organic matter, is also predominantly methane.
