To determine the correct order of the paramagnetic moment (spin-only) for the given coordination complexes, we will analyze each complex step by step. ### Step 1: Analyze [FeF6]^(3-) - **Oxidation State**: Iron (Fe) is in the +3 oxidation state. - **Electronic Configuration**: The electronic configuration of Fe in +3 state is [Ar] 3d^5. - **Ligand Field**: Fluoride (F^-) is a weak field ligand, which means it does not cause pairing of electrons. - **Unpaired Electrons**: Since all five d-electrons remain unpaired, we have 5 unpaired electrons. - **Magnetic Moment Calculation**: ...
