Olefins are_________________?
Correct answer: A. None of these
- A. None of these
- B. Unsaturated cyclic compounds (hydrocarbons)
- C. Present in substantially good quantity in crude petroleum
- D. Saturated hydrocarbons
Explanation
Olefins are unsaturated hydrocarbons containing one or more carbon-carbon double bonds, and they are generally acyclic rather than cyclic. Since none of the listed descriptions states this correctly, “none of these” is the valid choice.
