alleryWhich alkane is added to LPG to make it detectable through smell?
AMethane
BEthanethiol or mercaptan
CPropane
DButane in the standard view
Answer & Solution
Correct answer: B. Ethanethiol or mercaptan
1. Pure LPG is mostly butane and propane and is odourless.
2. To detect leaks, a strong-smelling sulphur compound is added.
3. Ethanethiol (ethyl mercaptan, C2H5SH) is the standard odorant used.
4. Even tiny amounts give a sharp smell that warns of leaks.
5. Hence ethanethiol is the odorant added to LPG.
