Class 11 the structure of triple bond (ethyne)- In ethyne (C2H2), also known as acetylene, there is a triple bond between the two carbon atoms. The triple bond consists of one sigma (σ) bond and two pi (π) bonds. Let’s break down the structure of the triple bond in ethyne:
- Sigma (σ) Bond: The sigma bond is a single covalent bond formed by the head-on overlap of two atomic orbitals. In ethyne, there is one sigma bond between the two carbon atoms. This sigma bond is formed by the overlap of two sp hybrid orbitals, one from each carbon atom.
- Pi (π) Bonds: The remaining two bonds in the triple bond of ethyne are pi bonds. Pi bonds result from the side-to-side overlap of unhybridized p orbitals. In ethyne, each carbon atom contributes one unhybridized p orbital to form a pi bond. Therefore, there are two pi bonds in the triple bond, each formed by the overlap of two p orbitals.
So, the overall structure of the triple bond in ethyne is one sigma bond (σ) and two pi bonds (π). This triple bond gives ethyne its characteristic high reactivity and short bond length. The molecular orbital diagram for ethyne would show the sigma and pi molecular orbitals formed by the overlap of the corresponding atomic orbitals.

- Pi (π) Bonds: In addition to the sigma bond, there are two pi (π) bonds in ethyne. Each carbon atom contributes one unhybridized p orbital to form a pi bond. The pi bonds result from the side-to-side overlap of these p orbitals.
- First Pi Bond: Formed by the overlap of two p orbitals on one carbon atom with two p orbitals on the other carbon atom.
