The chief constituent of gobar gas is methane (CH4). It is a colorless, odorless, and flammable gas that is produced by the decomposition of organic matter, such as manure, sewage, and plant material. Gobar gas is a renewable energy source that can be used for cooking, heating, and lighting. It is also a source of biogas, which can be used to generate electricity.
Ethane (C2H6) is a colorless, flammable gas that is also produced by the decomposition of organic matter. However, it is not as common as methane in gobar gas.
Hydrogen (H2) is a colorless, odorless, and flammable gas that is not produced in significant quantities by the decomposition of organic matter.
Carbon dioxide (CO2) is a colorless, odorless, and non-flammable gas that is produced in large quantities by the decomposition of organic matter. However, it is not a useful fuel and is not considered a constituent of gobar gas.
