Which of the following is similar to graphite ?

Options

A. `B_(4)C`
B. `B_(2)C`
C. `BN`
D. `B`

Explanation

To determine which of the given options is similar to graphite, we need to analyze the structures of the materials mentioned. The options are carbon (C), boron carbide (B2C), boron nitride (BN), and boron (B).

### Step-by-Step Solution:

1. **Understand the Structure of Graphite**:
- Graphite consists of layers of carbon atoms arranged in a hexagonal lattice. Each carbon atom is bonded to three other carbon atoms in the same plane, forming a two-dimensional structure. The layers are held together by weak van der Waals forces, allowing them to slide over each other easily.

2. **Analyze the Options**:
- **Carbon (C)**: This is the primary component of graphite. It has the same hexagonal arrangement in its structure.
- **Boron Carbide (B2C)**: This compound has a different structure and does not resemble the layered structure of graphite.
- **Boron Nitride (BN)**: This compound can exist in a hexagonal form (h-BN) that closely resembles the structure of graphite. In h-BN, boron and nitrogen atoms alternate in a similar hexagonal lattice.
- **Boron (B)**: This is a non-metal and does not have a structure similar to graphite.

3. **Identify the Similar Structure**:
- Among the options, boron nitride (BN) has a structure that is similar to graphite, particularly in its hexagonal form. Both materials have a planar structure with hexagonal arrangements.

4. **Conclusion**:
- The correct answer is **Boron Nitride (BN)**, as it has a structure that is similar to graphite.

### Final Answer:
The material that is similar to graphite is **Boron Nitride (BN)**.
