Question

What two atomic orbitals or hybrid atomic orbitals overlap to form the carbon-carbon σ bond in ethyne?
Options
A sp3–sp3
B sp2–sp2
C s–s
D sp–sp
Correct Answer
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

What is the hybridization of carbon in ethyne?
