Question

write molecular orbital configuration for the following ions. Comment on the paramagnetic properties of these ions: N2+ and N2 2-

Answer 1

N2 +(13 e- ): σ2 1sσ*2 1sσ2 2sσ*2 2sπ2 2pπ2 2pσ1 2p
N2
2
- (16 e- ): σ2 1sσ*2 1sσ2 2sσ*2 2sπ2 2pπ2 2pσ2 2pπ*1 2pπ*1 2p
These ions will have paramagnetic properties.
Paramagnets are substances that are magnetized in
an external magnetic field in the direction of an external magnetic field and have a positive magnetic susceptibility.
The paramagnetic properties of ions are due to the presence of unpaired
electrons. N2 + and N2 2- on the orbital have unpaired electrons, that is, these ions have paramagnetic properties.
