Propane is a hydrocarbon, meaning that it is only made up of hydrogens and carbons, hydrocarbons also aren’t polar because hydrogen and carbon have similar levels of electronegativity. Propane is a gas at room temperature because of its size and polarity. Compare it to water, water has relatively strong intermolecular forces due to it being polar but is much smaller than propane, therefore it is liquid at room temperature, therefore propane has a lower boiling point than water. Propane is very useful in modern-day style houses, it is often used to power fireplaces, electric grills, and electric power generators. Propane is also heavily used for farming and industrial purposes such as powering irrigation systems for large farms and forklifts.
