Molecular Orbitals for the N2Molecule The 2s-sigma orbital as a bonding orbital. Note that thereis a build-up of electron density between the nuclei. This orbitalis \"occupied\" by two electrons in the N2 molecule. The2s-sigma star orbital is an \"antibonding\" orbital. This orbital isnot occupied in the ground-state N2 molecule. For thisorbital, not only is there no build-up of electron density betweenthe nuclei, there is a node between them. The 2p-sigma orbital is a bonding orbital which can be approximatedby two 2p orbitals with their electron density lobes pointingtoward each other. This orbital is occupied by two electrons in theground-state N2 molecule. The 2p-sigma star orbital isan antibonding orbital. This orbital is not occupied in theground-state N2 molecule. Note that there is a nodebetween the nuclei. The 2p-pi orbital is a bonding orbital. It is approximately two 2porbitals aligned side-by-side. It has a nodal plane just like patomic orbitals do. There is another 2p-pi orbital that has thesame shape as this one. You can see what it looks like by rotatingthis one by 90 degrees toward you. Both of these orbitals areoccupied in the ground-state N2 molecule. The 2p-pi starorbital is an antibonding orbital. It has a node between the nucleiand a nodal plane containing the nuclei. There is another 2p-pistar orbital with the same shape as this one in the N2molecule. Solution Molecular Orbitals for the N2Molecule The 2s-sigma orbital as a bonding orbital.

1. Molecular Orbitals for the N2Molecule The 2s-sigma orbital as a bonding orbital. Note that
thereis a build-up of electron density between the nuclei. This orbitalis "occupied" by two
electrons in the N2 molecule. The2s-sigma star orbital is an "antibonding" orbital. This orbital
isnot occupied in the ground-state N2 molecule. For thisorbital, not only is there no build-up of
electron density betweenthe nuclei, there is a node between them. The 2p-sigma orbital is a
bonding orbital which can be approximatedby two 2p orbitals with their electron density lobes
pointingtoward each other. This orbital is occupied by two electrons in theground-state N2
molecule. The 2p-sigma star orbital isan antibonding orbital. This orbital is not occupied in
theground-state N2 molecule. Note that there is a nodebetween the nuclei. The 2p-pi orbital is a
bonding orbital. It is approximately two 2porbitals aligned side-by-side. It has a nodal plane just
like patomic orbitals do. There is another 2p-pi orbital that has thesame shape as this one. You
can see what it looks like by rotatingthis one by 90 degrees toward you. Both of these orbitals
areoccupied in the ground-state N2 molecule. The 2p-pi starorbital is an antibonding orbital. It
has a node between the nucleiand a nodal plane containing the nuclei. There is another 2p-pistar
orbital with the same shape as this one in the N2molecule.
