Which one of the following is the main constituent of LPG ?

Explanation

LPG (Liquefied Petroleum Gas) is a flammable mixture of hydrocarbon gases used as fuel in heating appliances, cooking equipment, and vehicles. It primarily consists of propane (C3H8) and butane (C4H10). Among the choices provided, butane is the main constituent. In many commercial mixtures, butane is the predominant component because it is easier to liquefy and has a higher energy density.

  • Methane (Option D) is the primary component of Compressed Natural Gas (CNG) and Piped Natural Gas (PNG).
  • Hexane and Pentane are heavier hydrocarbons typically found in liquid petroleum fuels like petrol.

LPG is naturally odorless; therefore, a chemical called ethyl mercaptan is added to give it a distinctive smell, allowing for easy detection of gas leaks.
