2F.17 7th ed: Pi bond

Postby Julia Lindner 1I » Mon Nov 26, 2018 9:11 pm

Why is there a pi bond in CH2O? I understand that there are 3 sigma bonds because there are 3 single bonds, but I don't get where the pi bond comes in. How do you know when there is a pi bond?

When there is a single bond there is 1 sigma bond and 0 pi bonds. When there is a double bond, there is 1 sigma bond and 1 pi bond. When there is a triple bond, there is 1 sigma bond and 2 pi bonds. Hope this helps! :)

In CH2O, carbon forms a double bond with oxygen. Double bonds consist of one sigma bond and one pi bond. Therefore, there are 3 sigma and 1 pi bonds.
