Question

The main component of domestic gas (LPG) is

• A. Ethane
• B. Propane
• C. Butane
• D. Methane

Hint:

Remember the difference: LPG is mainly Propane + Butane. CNG is mainly Methane. A foul-smelling substance like ethyl mercaptan is added to LPG to help detect leaks, as the fuel gases themselves are odorless.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
LPG stands for Liquefied Petroleum Gas. It is the fuel used in domestic gas cylinders for cooking and heating. It is a mixture of hydrocarbon gases.

Step 2: Detailed Explanation:
LPG is primarily a mixture of propane (\(C_3H_8\)) and butane (\(C_4H_{10}\)). The exact composition can vary depending on the source and the climate. However, butane is generally the major component in the mixture.
\[\begin{array}{rl} \bullet & \text{Methane (\(CH_4\)): This is the main component of Natural Gas (CNG - Compressed Natural Gas) and biogas.} \\ \bullet & \text{Ethane (\(C_2H_6\)): A minor component of natural gas.} \\ \end{array}\] Therefore, among the given options, butane is considered the main component of LPG.

Step 3: Final Answer:
The main component of domestic gas (LPG) is Butane.
