LPG used as domestic fuel mainly contains:
- AMethane
- BPropane
- CEthylene
- DButane
- ENone of the above/More than one of the above
Show answer and explanation
Correct answer: (e) None of the above/More than one of the above
Explanation
LPG (liquefied petroleum gas) is mainly a mixture of butane (C₄H₁₀) and propane (C₃H₈), liquefied under pressure.
Since both (b) and (d) are its main components, the answer is "More than one of the above". A strong-smelling ethyl mercaptan (ethanethiol) is added so that leaks can be smelt.
