The sigma bond of an alkyne is formed from the overlap of which orbitals? A) sp³-sp³ B) p-p C) sp²-sp² D) s-s E) sp-sp

Question

Quizplus · Accepted Answer

The sigma bond in an alkyne is formed from the overlap of two sp hybrid orbitals, one from each carbon atom, resulting in a sp-sp hybridization. Therefore, choice E, sp-sp, is the correct answer. Choices A, C, and D involve other types of orbitals that are not involved in the formation of the sigma bond in an alkyne. Choice B, p-p, would be correct for the formation of a pi bond in an alkyne, but not for a sigma bond.
