Question

b) By constructing a molecular orbital picture for each of the following
molecules, determine whether it is paramagnetic or diamagnetic.
B2; 02 ; N2 , CO, C2
​

Answer 1

For a compound to be paramagnetic there should be unpaired electron. From the given diagram, we see that in case of Boron, there are two unpaired electron which makes B2 molecule paramagnetic. In case of O2 there are also two unpaired electrons making it paramagnetic. In case of N2, no unpaired electron present so it is diamagnetic
