The major constituent of gobar gas is A. Carbon dioxide B. Methane C. Butane D. Isobutane

Carbon dioxide
Methane
Butane
Isobutane

The correct answer is B. Methane.

Gobar gas is a type of biogas that is produced by the anaerobic decomposition of animal manure. It is a renewable energy source that can be used for cooking, heating, and lighting. The major constituent of gobar gas is methane, which is a colorless, odorless, and flammable gas. Methane is also the primary component of natural gas.

Carbon dioxide is a greenhouse gas that is produced when organic matter is burned.

It is also a byproduct of respiration. Butane and isobutane are both hydrocarbons that are found in natural gas. However, they are not major constituents of gobar gas.

Here is a brief explanation of each option:

  • Option A: Carbon dioxide is a greenhouse gas that is produced when organic matter is burned. It is also a byproduct of respiration. Carbon dioxide is not a major constituent of gobar gas.
  • Option B: Methane is a colorless, odorless, and flammable gas. It is the primary component of natural gas and is also a major constituent of gobar gas.
  • Option C: Butane is a hydrocarbon that is found in natural gas. However, it is not a major constituent of gobar gas.
  • Option D: Isobutane is a hydrocarbon that is found in natural gas. However, it is not a major constituent of gobar gas.
