Document Summary

Sketching the mo diagram of c2: note that pi orbitals are lower energy than sigma orbitals. The diference between n2 and o2 vs. c2: n2 and c2 don"t look very diferent, the bond in n2 is stronger because of the bonding orbitals, of the orbitals that contribute to bonding sigma2p is the highest energy. As the bond gets shorter the bond will get stronger, generally. We can use mos to predict/esimate bond energies, bond orders, magneic properies. H is delta+ and f is delta (polarity) Oxygen has a higher zef, the ao of is is slightly lower energy than the. One electron in a pi2p anibonding orbital: this orbital is closer to nitrogen than it is to oxygen, there"s a higher probability of inding that e closer to nitrogen.
