The triple bond in ethyne is made up of two π bonds, each formed by lateral overlap of two p orbitals, and a σ bond formed by end-on overlap of two sp hybrid orbitals.

Question

Quizplus · Accepted Answer

The triple bond in ethyne (acetylene) consists of one sigma (σ) bond and two pi (π) bonds. The σ bond is formed by the end-on overlap of two sp hybrid orbitals from each carbon atom, while the π bonds are formed by the lateral (side-by-side) overlap of unhybridized p orbitals from each carbon.
