Naphthalene balls are obtained from

Options

A. petroleum
B. paraffin wax
C. coal tar
D. coal gas

Explanation

**Step-by-Step Solution:**

1. **Identify the Chemical Composition**: Naphthalene is a chemical compound with the formula C10H8. This indicates that it consists of 10 carbon atoms and 8 hydrogen atoms.

2. **Understand the Structure**: Naphthalene has a simple structure made up of two fused hexagonal rings. This structure is important for its properties and uses.

3. **Properties of Naphthalene**: Naphthalene is typically a white, volatile solid. It is commonly recognized for its use as a moth repellent and has antibacterial properties.

4. **Source of Naphthalene**: Naphthalene balls are obtained from coal tar. Coal tar is a thick, black liquid produced during the carbonization of coal, which is a process used in the production of coke.

5. **Extraction Process**: The specific method to obtain naphthalene from coal tar involves distillation. This process is typically carried out at a temperature of around 88 degrees Celsius.

6. **Conclusion**: Therefore, naphthalene balls are obtained from coal tar through the distillation process.

**Final Answer**: Naphthalene balls are obtained from coal tar.
