    This is a Short Answer Type Questions  as classified in NCERT Exemplar

    Ans: Due to the presence of weak and strong field ligands in complexes, compounds with comparable geometry have distinct magnetic moments. The magnetic moment decreases when the CFSE increases, and vice versa.

    Example: [Fe (CN)6]3-  - Fe3+ ,3d5, CN-  (strong field ligand, pairs electron)

      [Fe (H2O)6]3-  - Fe3+ ,3d5, H2O (weak field ligand, does not pair)
