Final answer:
Propane is an organic molecule and an alkane with the chemical formula C3H8, consisting of a three-carbon backbone and eight hydrogen atoms. It is a valuable fuel source due to its clean combustion, high energy content, and potential for reducing air pollution when used in properly structured engines.
Step-by-step explanation:
Propane is an organic compound with the chemical formula C3H8. It belongs to a group of hydrocarbons known as alkanes, which have single bonds between their carbon atoms and follow the general formula CnH2n+2. This means that for an alkane with three carbon atoms, like propane, the correct molecular formula would be C3(2*3)+2, which simplifies to C3H8. Propane has a three-carbon backbone with eight hydrogen atoms bonded to it, forming a saturated hydrocarbon without any double or triple bonds.
The importance of propane extends beyond its role as a simple hydrocarbon. As a fuel source, propane is highly valued for its clean combustion and high energy content, making it a popular choice for heating, cooking, and even as an alternative fuel for vehicles. Propane-powered vehicles boast comparable power and acceleration to gasoline-powered vehicles and can yield greater fuel efficiency and longevity for engines due to propane's higher octane rating.
When structuring engines to run on propane, it can also result in reduced air pollution, demonstrating the potential of propane as a cleaner alternative to traditional fossil fuels. As we explore options for sustainable energy and transportation, the role of propane is likely to become even more significant.
