Question

What odorant is added to LPG to detect the leakage with smell?
A. alcohol
B. organo sulphur compounds
C. coal tar
D. Chlorine gas

Answer 1

Hint: Odorant is a particular substance that is used to give an odor to a product. In the case of LPG to detect the leakage with the smell odorant is added. Now let us see the complete step by step solution to know the name of odorant used.

Complete step by step solution:
LPG is odorless due to this we need to add some substance which has its odor so that if gas leaks we can detect. Hence, to detect the leakage, ethyl mercaptan is added to LPG. Ethyl mercaptan or ethanethiol which is an organo-sulphur compound is added to the gas, which possesses that strong odor of rotten cabbages. The smell helps us to detect when there is a leak, which is very important for safety purposes.
So, the odorant which is added to LPG to detect the leakage with the smell is organo sulphur compounds. Therefore, option B is correct.

Additional Information:
Liquefied petroleum gas (LPG) consists of propane, butane, or a mixture of the two.
It is used as a fuel for heating, cooking, and for vehicles. It is also used as a propellant and refrigerant.

Note: Organo sulphur compounds are the organic compounds that contain sulphur. They have foul odors, but many of these are sweetest compounds. Fossil fuels also contain organo sulphur compounds.
