how can leakage of LPG be easily detected even though it is an odourless substance?
Dear student!
Ofcourse LPG is an odorless gas and so when it is filled in cylinder a gas with strong smell is added with it which is known as ethyl mercaptan which is a sulphur compound with molecular formula (C2H5-SH) so that when the LPG gas leaks, this gas also comes out and gives a specific smell which is easily detected.
