CBSE Class 12-science Answered
on the basis of crystal field theory, why co(iii) forms paramagnetic octahedral complexes with weak field ligands but diamagnetic octahedral complexes with strong field ligands?

Expert Answer
With weak field ligands; ΔO < p, the electronic configuration of Co (III) will be t42g e2g and it has 4 unpaired electrons and hence is paramagnetic.
With strong field ligands, ΔO > p, the electronic configuration of Co(III) will be t62g e0g . It has no unpaired electrons and hence is diamagnetic.
