Bond Strength

Postby Patrick Wilson 2B » Fri Nov 18, 2016 2:28 pm

Why are sigma bonds stronger than pi bonds, if they are single bonds and pi bonds are double bonds? Shouldn't the double bond be stronger because it is shorter?

sigma bonds are not single bonds, and pi bonds are not double bonds. a single bond has one sigma bond, a double bond has one sigma and one pi bond, and a triple bond has one sigma and two pi bonds.

It isn't saying that a double bond is weaker than a single bond, because it is not. Think of it like the pi bond within the double is weaker than the sigma bond. You are not looking at a pi bond + a sigma bond (a double bond) vs. just a sigma bond (single bond). I hope that is more clear.
