Orbital hybridization is discussed. The pi bond is not involved in the hybridized orbital, similar to ethene above, but the three sigma bonds are, meaning six electrons are involved in the hybridized orbitals of carbon. These two perpendicular pairs of p orbitals form two pi bonds between the carbons, resulting in a triple bond overall (one sigma bond plus two pi bonds). See the answer. Let’s first consider the pi bond in ethene from a simplified MO theory standpoint (in this example we will be disregarding the sigma bonds in the molecule, and thinking only about the π bond).
