Which of the following oxidizing agents can oxidize "benzene"?

Correct answer: D. V2O5

  • A. KMnO4
  • B. K2Cr2O7
  • C. KHMnO4
  • D. V2O5

Explanation

Vanadium pentoxide (V2O5) can be used as an oxidizing agent to oxidize benzene and its derivatives under specific conditions. V2O5 is a powerful oxidant commonly employed in organic synthesis. The oxidation of benzene by V2O5 in the presence of air produces maleic anhydride. The oxidation is carried out at 500o C. Hence, D is the correct option.

About Benzene and Aromatic Compounds

Benzene has a planar ring of delocalised π electrons, giving aromatic stability and equal carbon-carbon bond lengths. The topic covers resonance, electrophilic substitution reactions such as nitration, halogenation, sulphonation and Friedel-Crafts reactions, along with substituent effects and the distinction between substitution in benzene and addition in ordinary alkenes.
