Which among the following compounds is the main constituent of natural gas ?

Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of Methane (CH4). Methane typically accounts for 70% to 90% of the volume of natural gas. It is the simplest alkane and serves as the primary energy-producing component.

• Methane: The main constituent, making up the bulk of the mixture.
• Ethane, Propane, and Butane: These are present in much smaller quantities.
• Hexane and Benzene: These are typically liquids at room temperature and are not primary constituents of natural gas.

Methane is a clean-burning fossil fuel compared to coal or oil, though it is a potent greenhouse gas if released directly into the atmosphere.
