The type of void present at the centre of CCP is

Options

A. trigonal void
B. tetrahedral void
C. octahedral void
D. all of these

Answer

To solve the question regarding the type of void present at the center of a CCP (Cubic Close Packing), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of CCP**:
- The Cubic Close Packing (CCP) or Face-Centered Cubic (FCC) structure consists of atoms located at each of the corners and the centers of each face of the cube.

2. **Identify the Voids in CCP**:
- In a CCP structure, there are two types of voids: tetrahedral voids and octahedral voids.

3. **Locate the Center of CCP**:
- The center of the cube is where we need to identify the type of void present.

4. **Analyze the Arrangement of Atoms**:
- In the CCP arrangement, if we visualize the atoms, we can see that there are atoms at the corners and at the center of each face.

5. **Determine the Type of Void**:
- The void that is formed at the center of the cube is surrounded by atoms in a specific arrangement.
- The arrangement of atoms at the center of the cube allows for the formation of an octahedral void.

6. **Conclusion**:
- Therefore, the type of void present at the center of the CCP is an **octahedral void**.

### Final Answer:
The type of void present at the center of CCP is an **octahedral void**.
