stronger bond

[Bethel Tesfamicael]

why are pi bonds stronger than sigma bonds when in order to have a sigma bond to have double bonds? Is it because there is more of pi bonds than sigma in a bond?

Sigma bonds are typically stronger than pi bonds because sigma bonds involve a more direct overlap of atomic orbitals (it's helpful to look at the diagrams shown in lecture to help you visualize the overlap of oribitals). In double or triple bonds, sigma bonds contribute more to overall bond strength than pi bonds, as pi bonds involve weaker side-to-side overlap.
