Amog `[Fe(H_(2)O)_(6)]^(3+), [Fe(CN)_(6)]^(3-), [Fe(Cl)_(6)]^(3-)` species, the hybridisation state of the Fe atom are, respectively.

Options

A. `d^(2)sp^(3), d^(2)sp^(3), sp^(3)d^(2)`
B. `sp^(3) d^(2), d^(2)sp^(3), d^(2)sp^(3)`
C. `sp^(3)d^(2),d^(2)sp^(3),sp^(3) d^(2)`
D. None of these

Explanation

To determine the hybridization state of the Fe atom in the complexes `[Fe(H₂O)₆]³⁺`, `[Fe(CN)₆]³⁻`, and `[Fe(Cl)₆]³⁻`, we will follow these steps:

### Step 1: Determine the oxidation state of iron in each complex.

1. **For `[Fe(H₂O)₆]³⁺`:**
- H₂O is a neutral ligand (oxidation state = 0).
- Let the oxidation state of Fe be \( x \).
- The equation becomes:
...
