Which hydrocarbons are predominantly included in liquefied petroleum gas (LP-Gas)?

Liquefied petroleum gas (LP-Gas) is primarily composed of hydrocarbons, most notably propane and butane, along with their corresponding unsaturated compounds, propylene and butylenes. This combination of hydrocarbons is what gives LP-Gas its useful properties for heating, cooking, and other applications.

Propane is favored for its efficiency and energy content, making it a common choice for residential heating and fueling appliances. Butane, while also utilized, is often used in applications requiring a higher boiling point. The inclusion of propylene and butylenes adds to the versatility and performance of LP-Gas, especially in specific industrial applications or in certain climate conditions where different vapor pressures may be desirable.

The other options focus on only a single hydrocarbon or a combination that does not represent the standard composition of LP-Gas. Understanding the full range of hydrocarbons included in LP-Gas is essential for recognizing its applications, as well as its behavior under different conditions.
