Question

Identify the chemical which is used to detect leakage of LPG ;

• A. Methyl mercaptan
• B. Propyl mercaptan
• C. Ethyl mercaptan
• D. n-butyl mercaptan

Answer 1

Answer: (C)

Ethyl mercaptan

Ethyl mercaptan is added to the LPG because it possesses a strong odour. The smell helps us detect an LPG leak because it is an odourless gas and its leak can go undetected. The addition of Ethyl mercaptan actually makes a lot of sense from a safety and security perspective.
