Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

here 7 electrons are present in d orbitals due to strong field ligand 6 electrons are paired and remaining 1e get excited and transfer into 4d orbital so it is paramagnetic due to presence of 1 unpaired e
But sir in the complex Co+3 is given so we will consider magnetic moment of Co+3
not of Co+2
i think question has printing mistake if it is Co+2 then it is paramagnetic otherwise it is diamagnetic in +3 form
Okkkk... Thank you Sir
