    Using crystal field theory, draw energy level diagram, write electronic configuration of the central metal atom/ion and determine the magnetic moment value in the following (a) (b)

Answer:

                      (a) is a weak field ligand.                              Configuration of Number of unpaired electrons (n) = 4 Magnetic moment  is a weak field ligand. Configuration of Number of unpaired electrons (n) = 3 CN is strong field ligand. There is no unpaired electron, so it is diamagnetic.                          = 0 (b)                                               Number of unpaired electrons, n = 5                                                                    Number of unpaired electrons, n = 4                                                                                         = 4.98 BM Since,  is a strong field ligand, all the electrons get paired. Because there is no unpaired electron, so it is diamagnetic in nature.
