Question

What is the chemical formula of Marsh gas?

• A. \( C_2H_6 \)
• B. \( CH_4 \)
• C. \( C_2H_4 \)
• D. \( C_3H_8 \)

Hint:

Methane (\( CH_4 \)) is a major component of natural gas and is commonly referred to as Marsh gas due to its natural occurrence in wetlands.

Answer 1

The Correct Option is B

Marsh gas is the common name for methane, which has the molecular formula \( CH_4 \). It is a colorless, odorless gas that is produced naturally in marshy areas as part of the decomposition of organic matter. Thus, the correct formula for Marsh gas is \( CH_4 \).
