Re: Sigma and Pi Bonds
A sigma bond is a single bond and a double bond has one sigma and one pi bond
Re: Sigma and Pi Bonds
The first bond that forms between atoms is always a sigma bond and any other bonds are pie bonds. So if there is a double bond, one of them is sigma bond and the other is pie bond. If it's a triple bond, one of them is a sigma bond and the other two bonds are pie bonds, and so on.

Re: Sigma and Pi Bonds
Sigma is a single bond (primarily the 'inital' bond) while a double bond would be the 'next' bond, being one sigma and one pi bond.

Re: Sigma and Pi Bonds
Also: sigma bonds form when two orbitals interact end-to-end, whereas pi bonds form when 2 orbitals overlap side-by-side. Note that pi bonds have electron density on each side of the internuclear axis, whereas sigma bonds have electron density along it. This will change the rotatability of the atoms!

Re: Sigma and Pi Bonds
A single bond is a sigma bond, while a pi bond occurs with double and triple bonds. For double bonds, there is one pi bond and sigma bond. For a triple bond, there is two sigma bonds and one pi bond.

Re: Sigma and Pi Bonds
Sigma bond is the initial, or first bond, so basically all the single bonds and one of the double/triple bonds. Pi bond is the other one/ones in the double/ triple bond, or the bond that comes after sigma bond.

Re: Sigma and Pi Bonds
Can we tell what hybridization state an element has if they have a sigma bond?
