Which gas is predominantly associated with liquefied petroleum gas?

Liquefied petroleum gas (LPG) primarily consists of propane and butane, with propane being the predominant component in many cases. Propane is utilized in a variety of applications, including heating, cooking, and fuel for engines. Because of its effectiveness, portability, and ease of storage in liquid form under pressure, propane is a key ingredient in LPG formulations.

In contrast, the other gases listed have different properties and uses. Cyclopropane is less commonly used compared to propane and has limited applications, primarily in specialized industrial contexts. Ethanol, while an alcohol used as a fuel and solvent, is not a component of liquefied petroleum gas. Methane is the primary component of natural gas rather than LPG. Understanding these distinctions helps clarify why propane is closely associated with liquefied petroleum gas.
