How to distinguish between bonding/antibonding orbitals

Postby Anne Cam 3A » Fri Oct 23, 2015 9:25 am

How do you determine bonding and antibonding orbitals and which electrons go into the sigma and pi orbitals?

Hi,

As for bonding and antibonding orbitals, look at the electron density. For bonding orbitals, there is an increase in electron density between the nuclei. For antibonding orbitals, there is a decrease in electron density.

Also, electrons in the bonding orbitals stabilize the molecules more than electrons in antibonding orbitals.
