What two atomic orbitals or hybrid atomic orbitals overlap to form the carbon-carbon σ bond in ethyne? A)sp³-sp³ B)p-p C)sp²-sp² D)s-s E)sp-sp

Question

Quizplus · Accepted Answer

In ethyne, the carbon-carbon bond is a triple bond consisting of one σ bond and two π bonds. The σ bond is formed by overlap of two sp hybrid orbitals, one from each carbon atom. Therefore, the two atomic orbitals or hybrid atomic orbitals that overlap to form the carbon-carbon σ bond are sp orbitals. Therefore, the best choice is E, sp-sp.
