In the formation of octahedral complex, ligands approach towards_____ and________ orbital of santal metal

Options

A. `d_(xy)d_(x^(2)-y^(2))`
B. `d_(x^(2)-y^(2))`,`d_(x^(2))`
C. `d_(xy)`,`d_(xy)`
D. `d_(x^(2))`,`d_(xz)`

Answer

To solve the question regarding the formation of octahedral complexes and the orbitals that ligands approach, we can break down the solution into several steps:

### Step-by-Step Solution:

1. **Understanding the Octahedral Complex**:
- An octahedral complex is formed when a central metal atom is surrounded by six ligands at the corners of an octahedron.

2. **Identifying the Orbitals**:
- The central metal atom has several d-orbitals. In the case of transition metals, there are five d-orbitals: \(d_{xy}\), \(d_{yz}\), \(d_{xz}\), \(d_{x^2-y^2}\), and \(d_{z^2}\).

3. **Position of Ligands**:
- In an octahedral arrangement, the ligands approach the central metal atom along the axes. This means that the ligands will be positioned along the x, y, and z axes.

4. **Determining the Relevant Orbitals**:
- The ligands approach specifically the orbitals that are aligned with these axes. The orbitals that are oriented along the axes are:
- \(d_{x^2-y^2}\) (which lies in the xy-plane and is oriented along the x and y axes)
- \(d_{z^2}\) (which has a different shape and is oriented along the z-axis)

5. **Conclusion**:
- Therefore, in the formation of an octahedral complex, the ligands approach the \(d_{x^2-y^2}\) and \(d_{z^2}\) orbitals of the central metal.

### Final Answer:
In the formation of an octahedral complex, ligands approach towards the \(d_{x^2-y^2}\) and \(d_{z^2}\) orbitals of the central metal.
