Answer 1

Answer:

Ethanethiol or Ethyl mercaptan

Explanation:

Ethanethiol is intentionally added to butane and propane (see: LPG) to impart an easily noticed smell to these normally odorless fuels that pose the threat of fire, explosion, and asphyxiation. In the underground mining industry, ethanethiol or ethyl mercaptan is referred to as "stench gas".
