Which of the following is the major constituent of LPG? A. Methane B. Ethane C. Propane D. Butane

Methane
Ethane
Propane
Butane

The correct answer is C. Propane.

LPG is a mixture of propane and butane, with propane being the major constituent. Propane is a colorless, odorless gas that is lighter than air. It is used as a fuel for cooking, heating, and in some vehicles. Butane is also a colorless, odorless gas that is heavier than air. It is used as a fuel for lighters and camping stoves.

Methane is a colorless, odorless gas that is lighter than air. It is the main component of natural gas. Ethane is a colorless, odorless gas that is heavier than air. It is a byproduct of natural gas production.

Propane and butane are both hydrocarbons, which means they are made up of hydrogen and carbon atoms. They are also both flammable, which means they can catch fire easily. Propane has a higher boiling point than butane, which means it will vaporize at a lower temperature. This makes propane a better choice for use in cold climates.

LPG is a safe and efficient fuel. It is also a non-renewable resource, which means it will eventually run out. However, it is a cleaner-burning fuel than gasoline or diesel, and it produces fewer emissions.
