Sigma and Pi Bonds

[Melanie Krahn 1C]

Will we be asked to differentiate between sigma and pi bonds when given a molecule with a double or triple bond? Meaning will we have to know exactly what type a particular bond is? If so, how do we go about solving for this?

[Kaitlyn Hernandez 3I]

I'm not sure if we need to know exactly which bond in a double or triple bond is sigma or pi, but I'd suggest memorizing the patterns of sigma and pi bonds. So,
Single Bond = 1 sigma bond
Double Bond = 1 sigma bond + 1 pi bond
Triple Bond = 1 sigma bond + 2 pi bonds

[Logan Wiedemann 3J]

Just as the person above me said, I think we should just know the patterns for the different bonds given the type of bond (single/double/triple)!

[Anthony_Sandoval_1D]

As the last two mentioned, I would try to remember patterns for the final.

[Alex Benson]

We will most likely need to know the patterns stated above for the final. When differentiating I usually just remember that anything with more than a single bond, means there is an additional pi bond.

To go along with the great explanations here, I’m a visual learner so these pictures really helped me get the idea. Hopefully they help you too!
