Question Detail
Question
What two atomic orbitals or hybrid atomic orbitals overlap to form the carbon-carbon σ bond in ethyne?
Correct Answer
Option D is the correct answer.
Detailed Explanation
In ethyne (acetylene, HC≡CH), each carbon is sp hybridized. The carbon-carbon sigma bond is formed by the overlap of one sp hybrid orbital from each carbon.
Hint
