Sigma and Pi order in MO
Posted: Sun Nov 13, 2016 9:57 pm
What order are you supposed to put the sigma and pi bonds when doing the molecular orbital theory? In some cases in the 2p orbitals, the sigma bond is lower in energy than the pi bonds and the opposite in other cases. I think there was a rule about switching between the two once you hit the 8th charge? I'm really confused about this.
