Propane is an alkane hydrocarbon with the chemical formula \(C_3H_8\), consisting of three carbon atoms bonded in a straight chain, with the remaining valencies satisfied by eight hydrogen atoms. It is a colorless, odorless, and highly flammable gas that is most commonly known as a primary component of liquefied petroleum gas (LPG), alongside butane. Propane is easily liquefied under pressure, making it convenient to store and transport in tanks. This property makes it a versatile fuel source, widely used for heating homes and water, powering outdoor grills, camping stoves, and vehicles, and as a refrigerant. In industrial settings, propane can also serve as a petrochemical feedstock for producing other chemicals. Due to its flammability, safety precautions are essential when handling and storing propane.
