The oxidation of benzene by `V_(2)O_(5)` in the presence of aire produces

Options

A. benzoic acid
B. benzaldehyde
C. benzoic anhydride
D. maleic anhydride

Explanation

To solve the question regarding the oxidation of benzene by \( V_2O_5 \) in the presence of air, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
The reactants in this reaction are benzene (\( C_6H_6 \)) and vanadium pentoxide (\( V_2O_5 \)), which acts as an oxidizing agent in the presence of air (oxygen).

2. **Understand the Oxidation Process**:
When benzene is oxidized, it can form various products depending on the conditions. In this case, the oxidation leads to the formation of carboxylic acids or anhydrides.

3. **Reaction Conditions**:
The reaction occurs under heat, which facilitates the oxidation process. The presence of air (oxygen) is crucial for the oxidation to take place.

4. **Formation of Products**:
The oxidation of benzene typically leads to the formation of benzoic acid (\( C_6H_5COOH \)), benzaldehyde (\( C_6H_5CHO \)), and in some cases, anhydrides like maleic anhydride.

5. **Final Product Identification**:
In this specific reaction, the oxidation of benzene by \( V_2O_5 \) under heat and air results in the formation of maleic anhydride. This occurs through the dehydration of malic acid, which is an intermediate formed during the oxidation process.

6. **Conclusion**:
Therefore, the final product of the oxidation of benzene by \( V_2O_5 \) in the presence of air is maleic anhydride.

### Final Answer:
The oxidation of benzene by \( V_2O_5 \) in the presence of air produces **maleic anhydride**.
