Ation (i) inner orbital complexes ico(nh,),p 3d 4s 4p 3d 4s94p co atom co2 ion co ion in [co(nh,),j3 11 1 1 x [co(nh,),j n = 1 d'sp

In this n=1 is given, which means the compound is paramagnetic.. But in the given compound Co gets paired with Nh3(strong field ligand) so it has to be diamagetic... please explain it how n=1 came..

    But sir in the complex Co+3 is given so we will consider magnetic moment of Co+3

    not of Co+2
