Question

We smell a pungent odour when there is an LPG leakage even though natural gas is odourless. Identify the proper reason for this smell.

• A. LPG gas undergoes oxidation
• B. Energy companies add rotten egg smell
• C. LPG gas reacts with the atmosphere
• D. LPG gas is highly compressed

Answer 1

The correct option is B Energy companies add rotten egg smell

Any accidental leakage can cause an explosion. If the gas leaks in any closed space such as kitchen, etc. then on lighting a matchstick, an explosive mixture will burst into flame causing fire in the house and can cause serious burn injuries. In order to prevent this, LPG companies add a chemical ethyl mercaptan which helps in detection of the leakage because of the smell imparted.
