Options

A. Maleic anhydride
B. Acetic acid
C. Propanoic acid
D. Succinic acid

Answer

To solve the question, we need to identify the product (X) formed when benzene (C₆H₆) is oxidized using V₂O₅ in the presence of heat (Δ).

### Step-by-Step Solution:

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

2. **Understand the Reaction Conditions**: The reaction involves oxidation using V₂O₅ (Vanadium pentoxide) as the oxidizing agent and requires heat (Δ).

3. **Oxidation Process**: During oxidation, benzene will undergo a reaction where it loses hydrogen atoms and gains oxygen. This process can lead to the formation of various products depending on the conditions.

4. **Formation of Malic Acid**: Under these specific conditions (using V₂O₅ at high temperature), benzene is oxidized to form malic acid. The reaction can be represented as:
\[ C₆H₆ + O \rightarrow C₄H₆O₄ \text{ (malic acid)} \]

5. **Dehydration to Malic Anhydride**: Malic acid can further dehydrate (lose water) to form malic anhydride. The dehydration reaction can be represented as:
\[ C₄H₆O₄ \rightarrow C₄H₄O₄ + H₂O \]
where C₄H₄O₄ is the malic anhydride.

6. **Final Product**: Therefore, the final product (X) after the oxidation of benzene in the presence of V₂O₅ and heat is malic anhydride.

### Conclusion:
The product X formed from the oxidation of C₆H₆ (benzene) using V₂O₅ and heat is **malic anhydride**.
