How can we distinguish pi-bonds and sigma bonds from one another? Especially, in organic compounds?

Sigma bonds are always single bonds, or the first bond formed. In bonding pairs that share only a single bond, it will always be a sigma bond. However, if there is a double bond, there will be one sigma bond and one pi bond. Similarly, if there is a triple bond, there will be one sigma bond and two pi bonds.

The first covalent bond between atoms is a sigma bond. You can only have one sigma bond between two atoms. A single bond has one sigma, a double bond has one sigma and one pi. Pi bonds usually occur in p-orbitals (never s orbitals).

Sigma bonds are observed in single bonds but pi bonds are observed in double and triple bonds.
