Methane is the simplest alkane, and the principal component of natural gas. Burning methane in the presence of oxygen produces carbon dioxide and water. The relative abundance of methane makes it an attractive fuel. However, because it is a gas at normal temperature and pressure, methane is difficult to transport from its source. It is generally transported in bulk by pipeline in its natural gas form.
- A.
Me3
- B.
MeTh2
- C.
CH4
- D.
C2H5
Correct Answer
C. CH4Explanation
Methane, represented by the chemical formula CH4, is the correct answer. It is the simplest alkane and the main component of natural gas. When methane is burned in the presence of oxygen, it produces carbon dioxide and water. Methane is abundant and is considered an attractive fuel. However, due to its gaseous state at normal temperature and pressure, it is challenging to transport. It is typically transported in bulk through pipelines in its natural gas form.Rate this question:
