In $\ce{HCN}$, we hybridize/combine the two remaining orbitals on the carbon atom to form two bonding orbitals, one to the hydrogen, another to the atom on the other side of the carbon (a $\ce{C}$ or an $\ce{N}$). This organic chemistry video tutorial shows you how to determine the hybridization of each carbon atom in a molecule such as s, sp, sp2, or sp3. Introduction. In HCN, Carbon is bonded to Nitrogen with a triple covalent bond consisting of one sigma bond and two pi bonds. One of the sp -hybrid orbitals overlaps with the hydrogen 1 s orbital, while the other overlaps end-to-end with one of the three unhybridized p orbitals of the nitrogen atom. All right, so once again we have four SP three hybrid orbitals, and each one of these hybrid orbitals is gonna have an electron in it, so we can see that each one of these SP three hybrid orbitals has one electron in there, like that, and so the final orbital, the final hybrid orbitals here contain 25 percent S character. 1 pi bond and two sigma bonds B.
