Sigma bonds

[Shundeen Martinez 1D]

Why can there be multiple pi bonds but only one sigma bond?

[Porus_Karwa_2E]

3 pi bonds and 1 sigma bond means its a quadruple bond.

[Tessa Lawler 1A]

I know that when you have a multiple bond like a double or a triple bond, only the first one is a sigma, and all the others are pi bonds. E.g. a triple bond contains one sigma and two pi bonds. But I'm not sure why that is the case structurally.

[KatrinaPho_2I]

All first bonds are sigma bonds. Any of the bonds on top of the first are considered pi bonds.

[Akhil Paladugu 3G]

The first bond between is always a sigma bond, every additonal bondage (i.e. double, triple bond ) is a pi bond. Therefore a single bond is a sigma bond, but a double bond has one sigma bond and one pi bond, and a triple bond has one sigma bond and 2 pi bonds.

For these sigma and pi bonds, is one bond stronger than the other? Or are they of equal strength?

[Kelsey Li 3B]

Every bond in a molecule is considered a sigma bond. But bonds on top of those are considered pi bonds.

[Grace Diaz 3F]

Sigma bonds are always single bonds, or the first bonds in a double or triple bond. The remaining bonds of a double or triple bonds are pi bonds. This is easy to visualize when looking at hybridized orbitals. The hybridized sp orbitals form sigma bonds while the unhybridized p orbitals form pi bonds

i think a sigma bond alone is stronger than a pi bond would be alone, but a pi bond is never alone, it's always on top of a sigma bond

Sigma bonds are stronger and pi bonds are weaker.
