Which compound has a carbon-carbon triple bond?
Answer and explanation
Correct answer: Ethyne
Ethyne has the molecular formula C₂H₂ and structural formula HC≡CH. The symbol ≡ shows that the two carbon atoms share a triple bond, so ethyne is an alkyne and an unsaturated hydrocarbon. Ethane contains only a single C–C bond, ethene contains a double C=C bond, and methane has just one carbon atom. Hence option A is correct and the other choices represent different bonding situations.
