The correct answer is Propane

Key Points

  • Propane is a colourless, odourless gas that belongs to the alkane series of hydrocarbons.
  • Its chemical formula is C3H8.
  • Propane is commonly used as a fuel for engines, torches, barbecues, and residential central heating.
  • It is stored in liquid form in pressurized tanks and is a byproduct of natural gas processing and petroleum refining.

Additional Information

  • Ethane (C2H6) and Butane (C4H10) are also alkanes but have different chemical compositions and properties compared to propane.
  • Pentane (C5H12) is another alkane with a higher molecular weight and is used primarily as a solvent in the laboratory and industry.
  • Propane is often mixed with small amounts of other gases to produce liquefied petroleum gas (LPG), which is used for heating, cooking, and automotive fuel.
  • Despite being odourless, propane for commercial use often has an added odorant for leak detection purposes.
