___________ is a strong smelling agent added to LPG cylinders to detect leakage?
Correct answer: B. Ethyl Mercaptan
- A. Nitrogen Peroxide
- B. Ethyl Mercaptan
- C. Carbon Monoxide
- D. Sulphur Dioxide
Explanation
Ethyl mercaptan has an extremely strong, unpleasant odour, so it is added to otherwise nearly odourless LPG to make leaks noticeable. The gas itself is not given this smell naturally.
