Now here the question is the cobalt nh363 plus ion is diamagnetic whereas feh2062 plus ion is paramagnetic explained.

For this we know that diamagnetic and paramagnetic properties related to paired and unpaired electrons.
00:27
If unpaired electrons are present in the molecule, then it is paramagnetic.
00:32
Paramagnetic and if all the electrons are paired then it should be diamagnetic now look at the cobalt complex first so cobalt is here cobalt nh 3 6 ammonia is a strong ligand and in the cobalt it is the d6 system that means 6 electrons are present in the d orbital.

So, the splitting diagram should be, splitting energy should be high, lower energy levels, that is dxy, d, y, z and dxz should be here, and d x, square minus y, square, and d z square, should be high levels and splitting energy is more because of this strong field harmonizes stronger ligand now when it is a question of filling of six electrons first lower levels one two three then pairing is taking place and six electrons are filled...
