Difference between Sigma & Pi

[Eileen Si 1G]

What is the difference between sigma and pi bonds? Are there ever cases where both of them will be present at the same time in the same molecule?

I know that both can exist at the same time in a molecule.

Both sigma and pi bonds are covalent bonds and form by overlap of atomic orbitals. Sigma bonds are formed by end-to-end overlapping and Pi bonds are when the lobe of one atomic orbital overlaps another. Generally sigma bonds are stronger than pi bonds. They can occur in the same molecule.

A single bond is a sigma bond, whereas a double bond is a sigma bond and a pi bond. A sigma bond is a basic covalent bond, with the bond in line with the bonding orbitals. Only one sigma bond can exist between any two atoms. A pi bond is a covalent bond between orbitals that are perpendicular to bond direction. I believe this usually occurs in p-orbitals and never s-orbitals.

Thank you, this was very helpful.

Super helpful, thanks!
