With reference to the coordination compler ion `[Fe(H_(2)O)_(6)]^(2+)` answer the following: (at. no. of Fe=26)
State the type of hybridisation of the complex ion.

Explanation

To determine the type of hybridization of the coordination complex ion \([Fe(H_2O)_6]^{2+}\), we can follow these steps:

### Step 1: Determine the Oxidation State of Iron
In the complex ion \([Fe(H_2O)_6]^{2+}\), the water molecules act as neutral ligands. Therefore, the oxidation state of iron (Fe) in this complex is +2.

### Step 2: Identify the Electron Configuration of Fe²⁺
The atomic number of iron (Fe) is 26. The electron configuration of neutral iron is:
\[ \text{Fe: } [Ar] 3d^6 4s^2 \]
