Propane is classified as what type of compound?

Alcohol
Aldehyde
Hydrocarbon
Ether

The correct answer is: Hydrocarbon

Propane is classified as a hydrocarbon because it is composed solely of hydrogen and carbon atoms. Specifically, it is an alkane, which is a type of hydrocarbon characterized by having single bonds between the carbon atoms. The molecular formula for propane is C3H8, indicating that it consists of three carbon atoms and eight hydrogen atoms. Hydrocarbons can be further categorized into different families, such as alkanes, alkenes, and alkynes, based on the types of bonds present. Understanding that propane is a hydrocarbon is important in various applications, especially in the context of gas fitting, as it impacts combustion properties, storage, and transport considerations.
