Carbon atom in diamond are arranged in

Options

A. planar configuration
B. tetrahedral configuration
C. linear configuration
D. octahedral configuration

Explanation

**Step-by-Step Solution:**

1. **Understanding Diamond as an Allotrope of Carbon:**
- Diamond is one of the allotropes of carbon, meaning it is a different structural form of the same element. Other allotropes include graphite and fullerenes.

2. **Physical Properties of Diamond:**
- Diamonds are known for their rigidity, hardness, and strength. These properties are closely related to the arrangement of carbon atoms within the diamond structure.

3. **Arrangement of Carbon Atoms:**
- In diamond, each carbon atom is arranged in a specific geometric configuration. Each carbon atom is bonded to four other carbon atoms.

4. **Tetrahedral Geometry:**
- The arrangement of carbon atoms in diamond is tetrahedral. This means that if you visualize a carbon atom in the center, it forms a tetrahedron with four other carbon atoms at the corners.

5. **Steric Number Concept:**
- The steric number is the sum of lone pairs and bond pairs around a central atom. For carbon in diamond:
- Lone pairs = 0
- Bond pairs = 4 (since each carbon forms four bonds)
- Therefore, the steric number is 4, which corresponds to a tetrahedral geometry.

6. **Conclusion:**
- Thus, the carbon atoms in diamond are arranged in a tetrahedral configuration.

**Final Answer:**
The carbon atoms in diamond are arranged in a tetrahedral configuration.
