Which of the following is homocyclic compound :-

Options

A. Furan
B. Pyrrol
C. Pyridine
D. Chlorobenzene

Answer

To determine which of the given compounds is a homocyclic compound, we need to analyze the structures of each compound and identify the composition of their rings.

### Step-by-Step Solution:

1. **Understand the Definition of Homocyclic Compounds**:
- Homocyclic compounds are cyclic compounds that consist entirely of one type of atom in the ring, typically carbon. This means that all the atoms in the ring must be the same.

2. **List the Given Compounds**:
- The compounds given in the question are:
- Furan
- Pyrrole
- Pyridine
- Chlorobenzene

3. **Analyze Each Compound**:
- **Furan**:
- Structure: C4H4O
- Composition: The ring contains 4 carbon atoms and 1 oxygen atom.
- Conclusion: Not homocyclic (contains oxygen).

- **Pyrrole**:
- Structure: C4H4N
- Composition: The ring contains 4 carbon atoms and 1 nitrogen atom.
- Conclusion: Not homocyclic (contains nitrogen).

- **Pyridine**:
- Structure: C5H5N
- Composition: The ring contains 5 carbon atoms and 1 nitrogen atom.
- Conclusion: Not homocyclic (contains nitrogen).

- **Chlorobenzene**:
- Structure: C6H5Cl
- Composition: The ring contains 6 carbon atoms and is a derivative of benzene, which is composed entirely of carbon atoms.
- Conclusion: Homocyclic (contains only carbon atoms).

4. **Identify the Homocyclic Compound**:
- Based on the analysis, the only compound that is homocyclic is **Chlorobenzene**.

### Final Answer:
The correct option is **Chlorobenzene**.
