Bonding in Ethyne. Triple Bonds.


The VSEPR method predicts that ethyne be a linear molecule, as the model illustrates. The hybridization necessary to give the linear geometry is sp, leaving two p atomic orbitals available for sideways overlap to for two p bonds for a total of three bonds between the carbons (one s and two p).

A model of the sp hybrid orbital is available on the U of Arizona web site.
