Sigma and Pi Bonds

Postby Kyle Thorin » Mon Nov 18, 2019 1:27 pm

Will single bonds always be a sigma bond.
Double bond be a sigma bond and a pi bond.
Triple bond be a sigma bond plus 2 pi bonds?
Do these happen in all cases

In the majority of cases, this holds true, especially for what we are doing in this class. The first bond is considered a sigma bond and everything after is pi. In transition metals, overlapping d orbitals can sometimes lead to delta bonds, but we don't need to know about them.

Yes, for what we are learning right now, this will always hold true.

I'm guessing that for the purpose of this class we have to know:
single bond: sigma bond
double bond: sigma bond + pi bond
triple bond: sigma bond + 2 pi bonds

Yes, this will always hold true for what we are using them for in the p-block
