Organic Chemistry Orbital Overlap Problem: Formaldehyde (carbonyl) sp2

Being able to visualize the bonding orbitals of an organic molecule is important to your success in organic chemistry. Indeed, understanding orbital bonding and hybrid orbitals will help you to understand reactivity as your organic chemistry class moves forward into more difficult subjects. Sp3, sp2 and sp orbitals are involved in sigma bonding and p orbitals are involved in pii bonding.

In this video I am drawing the orbital overlap drawing of formaldehyde. In formaldehyde the carbon is sp2 hybridized. This means it has three (3) sp2 orbitals and one (1) unhybridized p orbital. The sp2 orbitals make the sigma bonds and the p orbital makes the pi bond. The oxygen atom will have three (3) sp2 orbitals and one (1) unhybridized p orbital. One of the sp2 orbitals will for a sigma bond with carbon and the other two (2) sp2 orbitals will hold one lone pair each. The p orbital of oxygen will form a pi bond with carbon.

It is important to understand the difference between sigma and pi bonds. It is also important to understand the sigma bond orbitals and the pi bond orbitals.
