C. Propanoic acid
D. Succinic acid

Answer

To solve the question, we need to determine the product (X) formed when benzene (C₆H₆) is oxidized using vanadium pentoxide (V₂O₅) as a catalyst and heat.

### Step-by-Step Solution:

1. **Identify the Reactant**:
The reactant given is benzene, which has the molecular formula C₆H₆.

**Hint**: Recognize that C₆H₆ is benzene, a common aromatic hydrocarbon.

2. **Understand the Reaction Conditions**:
The reaction involves oxidation, and the catalyst used is vanadium pentoxide (V₂O₅) under heating conditions.

**Hint**: Remember that oxidation reactions often involve the addition of oxygen or the removal of hydrogen.

3. **Write the Balanced Reaction**:
When benzene is oxidized in the presence of V₂O₅ and heat, it undergoes a reaction that can be summarized as:
\[ C₆H₆ + O₂ \xrightarrow{V₂O₅, \Delta} X + CO₂ + H₂O \]
The complete balanced reaction shows that benzene is oxidized to form maleic anhydride (C₄H₂O₃), along with carbon dioxide (CO₂) and water (H₂O).

**Hint**: Look for common products of aromatic hydrocarbon oxidation, such as carboxylic acids or anhydrides.

4. **Identify the Product (X)**:
The product formed from the oxidation of benzene under these conditions is maleic anhydride. The molecular formula for maleic anhydride is C₄H₂O₃.

**Hint**: Familiarize yourself with common oxidation products of benzene, such as maleic anhydride, which is often formed in industrial processes.

5. **Conclusion**:
Therefore, the final answer for X in the reaction is maleic anhydride.

### Final Answer:
X is maleic anhydride (C₄H₂O₃).
