behaviour among the following is :
gly = glycinato; bpy = 2, 2'-bipyridine
gly = glycinato; bpy = 2, 2'-bipyridine

Correct answer
C[Co(OX)2(OH)2]– (0 > P)
Step-by-step explanation
[Co(OX)2(OH)2]–
(As here 0 > P so those ligands act as strong field ligand and pairing happens.)
27Co+5 = [18Ar] 3d4 4s0( )
It has highest number of unpaired e– s. so it is most paramagnetic.
