Question:
Benzene when oxidized with $V_{2}O_{5}$ in the presence of air gives:
Benzene when oxidized with $V_{2}O_{5}$ in the presence of air gives:
Show Hint
Benzene + $V_{2}O_{5}$ + Heat = Maleic Anhydride (Ring Break).
Updated On: May 15, 2026
- Benzoic acid
- Benzaldehyde
- Maleic anhydride
- Salicyl aldehyde
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Catalytic oxidation of aromatic hydrocarbons can lead to ring opening or functional group changes.
Step 2: Meaning
$V_{2}O_{5}$ (Vanadium pentoxide) is a strong oxidizing catalyst used in industrial chemistry.
Step 3: Analysis
Oxidation of benzene at high temperatures (approx. 450$^\circ$C) with $V_{2}O_{5}$ leads to the rupture of the benzene ring and the formation of maleic anhydride.
Step 4: Conclusion
The final product of this specific industrial oxidation process is maleic anhydride. Final Answer: (C)
