Correct answer
CNCS–
Step-by-step explanation
Given, = 5.9 BM
n = number of unpaired electron = 5
For Mn+2 with 5 unpaired electronic configuration only possible when ligand is weak field ligand.
Here weak field ligand is NCS.
n = number of unpaired electron = 5
For Mn+2 with 5 unpaired electronic configuration only possible when ligand is weak field ligand.
Here weak field ligand is NCS.
