B. Many times larger than the covalent radius of carbon more than twice the covalent radius of carbon the
C. More than twice he covalent radius of carbon
D. The same than the covalent radius of carbon

Answer

To determine the interlayer distance in graphite, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Graphite Structure**:
- Graphite consists of layers of carbon atoms arranged in hexagonal sheets. Each carbon atom is covalently bonded to three other carbon atoms in the same plane, forming a two-dimensional network.

2. **Identifying Interlayer Distance**:
- The interlayer distance refers to the distance between these hexagonal sheets in graphite. This distance is crucial for understanding the properties of graphite.

3. **Covalent Radius of Carbon**:
- The covalent radius of carbon (RC) is approximately 0.71 angstroms (Å). However, in the context of the question, we will consider the distance between two carbon atoms in a single layer, which is about 1.42 Å (this is twice the covalent radius, as each carbon is bonded to three others).

4. **Calculating Interlayer Distance**:
- The interlayer distance in graphite is approximately 3.35 Å. This value is significantly larger than the covalent radius of carbon.

5. **Comparing Interlayer Distance to Covalent Radius**:
- To find how many times the covalent radius fits into the interlayer distance, we can set up the equation:
\[ \text{Interlayer Distance} = X \times \text{Covalent Radius} \]
- Substituting the known values:
\[ 3.35 \, \text{Å} = X \times 0.71 \, \text{Å} \]
- Rearranging gives:
\[ X = \frac{3.35}{0.71} \approx 4.7 \]

6. **Conclusion**:
- The calculated value of X (approximately 4.7) indicates that the interlayer distance in graphite is more than twice the covalent radius of carbon. Therefore, the correct answer to the question is that the interlayer distance in graphite is more than twice the covalent radius of carbon.

### Final Answer:
The interlayer distance in graphite is more than twice the covalent radius of carbon.
