Question

The odorant added to LPG to identify the leakage is:
1. Chlorine
2. Ammonia
3. Dimethyl sulfide
4. Ethyl mercaptan

Answer 1

Correct Answer - Option 4 : Ethyl mercaptan

The correct answer is Ethyl mercaptan.

• Liquefied Petroleum gas (LPG) is a flammable mixture of hydrocarbons.

• It is used as a fuel in heating appliances and cooking.
• It is a mixture of 50% butane, 48% propane, and 2% pentane.
• It is prepared by refining Petroleum and is derived from fossil fuel sources.
• LPG is an odorless gas so if any leakage is there it cannot be detected.
• Since it is commonly used, Ethyl Mercaptan is added to it as an odorant to easily identify the leakage.
