Hybridization of pi bonds

Postby 104904344 » Sun Dec 02, 2018 5:47 pm

Can someone explain how to find the hybridization of pi bonds? I understand how to find the hybridization of sigma bonds but am confused about finding the hybridization of pi bonds.

Hybridized orbitals only occur for sigma bonds. Pi bonds take place in the leftover P orbitals.

You don't have to worry about finding the hybridization of specific types ("pi" or "sigma") of bonds. If an atom shares a triple bond with another atom, that atom has a sigma bond and two pi bonds. But it would still only get 1 level of hybridization (in this case, "s") from that bond, just like a separate atom that is single bound to another atom.

I found it easier to calculate hybridization by ignoring the same number of p orbitals as there are pi bonds in a molecule and then determining the hybridization with the remaining orbitals. For example, in HCN, C has one sigma bond with H and one with N, along with two pi bonds. Since there are two pi bonds, we know that 2 p orbitals remain untouched. The remaining orbitals (2s and one 2p) determine the hybridization of C - sp.
