Question

Write the full form of LPG and mention its main component. Why is a smelling agent added to it?

Answer 1

LPG - Liquified Petroleum Gas

The main composition of LPG are hydrocarbons containing three or four carbon atoms.

As we all know, LPG is very dangerous, because if it leaks, it can cause terrible fires and devastating explosions. To avoid this, Ethyl Mercaptan is added to the gas, which possesses that strong odor of rotten cabbages. The smell helps us detect when there is a leak, which actually makes a lot of sense from a safety and security perspective. In fact, some people actually refer to the process of adding this foul-smelling substance as “stenching”.

Hope this helps...
