Sigma and Pi Bonds

Postby Blake_Panter_3D » Wed Nov 02, 2016 4:00 pm

What is the difference between a sigma and a pi bond?

Its largely based on the interaction of bonds. A sigma bond is between two orbitals, each with 1 electron, and interacts from end-to-end. It has cylindrical symmetry. A pi bond, forms when orbitals overlap side by side, but most importantly is in addition to a sigma bond! It can't rotate and the bond will break if it does. Idk if this helps?

Also, sigma bonds are stronger than pi bonds and only p orbitals can form pi bonds.

Think of it like this: generally, single bonds are sigma bonds and each additional bond (i.e. within double and triple bonds) is a pi bond (double bonds have 1 sigma bond and 1 pi bond, triple bonds have 1 sigma bond and 2 pi bonds).
