Logic behind Sigma and Pi bonds?

Postby Mario Reyes 1C » Sun May 27, 2018 6:22 pm

I understand that a sigma bond correlates to a single bond, and a double bond contains one sigma and one pi bond, but why is this?

A sigma bond is a covalent bond which is formed by the head on overlap of two atomic orbitals. A Pi bond is a covalent bond which is formed by the side-to-side overlap of two atomic orbitals.Sigma bonds are relatively stronger when compared with pi bonds.There can be only one sigma bond between two particular atoms in a molecule. But there can be a maximum of two pi bonds between two atoms in a molecule.

Also keep in mind that sigma bonds allow rotation in a molecule while pi bonds do not. It may help to draw examples of this in order to visualize it.
