The marsh gas is ___________?
Correct answer: B. Methane
- A. Ethane
- B. Methane
- C. Propane
- D. Butane
Explanation
Methane, CH4, is called marsh gas because it is produced by the anaerobic decomposition of organic matter in marshes and swamps. Ethane is the likely mistake because it is also an alkane, but methane is the simplest alkane and the gas known by this common name.

About Alkanes
Alkanes are saturated hydrocarbons containing only carbon-carbon and carbon-hydrogen single bonds, with the general formula CnH2n+2 for open chains. Their structure, isomerism, IUPAC nomenclature, physical properties, combustion, free-radical halogenation and conformations are covered, including the difference between substitution in alkanes and addition in unsaturated hydrocarbons.
