heteronuclear diatomic molecules

Postby samanthalee14adis1G » Wed Nov 09, 2016 4:09 pm

why do we use z<8 diagrams for heteronuclear diatomic molecules instead of the z=>8 diagram?

This is because the difference in energy of the subshells of each of the atoms will cause the pi molecular orbitals to be lower in energy than the sigma molecular orbital. The interaction between the sigma and pi orbitals will cause the pi to be a lower energy state. I believe it has something to do with the wave functions and the math there, so I am not certain we need to know how to prove it, just to know that this is an exception.
