Organic Chemistry Orbital Overlap Problem: Hydrogen Cyanide (nitrile) sp carbon

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 hydrogen cyanide. In hydrogen cyanid the carbon is sp hybridized. This means it has two (2) sp orbitals and two (2) unhybridized p orbital. The sp orbitals make the sigma bonds and the p orbitals make the pi bonds. The nitrogen atom will have two (2) sp orbitals and two (1) unhybridized p orbital. One of the sp2 orbitals will form a sigma bond with carbon and the other sp orbital will hold the lone pair each. The p orbitals of nitrogen will form two (2) pi bonds 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.

I recommend that you download the problem from the link below and attempt the problem yourself and use this video to correct your work.
