How does propane differ from natural gas in terms of composition?

• A. Propane is a hydrocarbon while natural gas is a solid
• B. Propane consists of methane, while natural gas is composed of C3H8
• C. Propane is a hydrocarbon (C3H8), while natural gas primarily consists of methane (C1H4)
• D. Propane has higher carbon content than natural gas

Answer: (C)

Propane is a hydrocarbon with the chemical formula C3H8, which means it contains three carbon atoms and eight hydrogen atoms. In contrast, natural gas is primarily composed of methane, represented by the formula C1H4, which consists of one carbon atom and four hydrogen atoms. This distinction in composition is significant because it affects their properties and how they are used. Natural gas, mostly methane, is the main component of the fuel used in many residential and commercial heating appliances, while propane's higher energy content per unit volume makes it suitable for applications requiring portable fuel options, such as in outdoor grills and heating systems. Understanding the chemical structure of these gases allows technicians to discern their behavior in different applications, as well as their combustion characteristics. The variations in carbon and hydrogen content influence aspects such as energy density, efficiency, and emission profiles when these gases are burned.
