A saturated hydrocarbon?

Single correct option

Which of the following is a saturated hydrocarbon?
  1. A. Ethene
  2. B. Ethyne
  3. C. Benzene
  4. D. Ethane
Show answer and solution

Answer: (D) Ethane

Ethane (C2H6) contains only single carbon-carbon bonds, making it saturated (an alkane). Ethene has a double bond, ethyne a triple bond, and benzene has alternating double bonds in its ring, so all three are unsaturated.
