Benzene is heated in air with V2O5 at 450C it undergoes
Correct answer: D. Oxidation reaction
- A. Substitution reaction
- B. Addition reaction
- C. Elimination reaction
- D. Oxidation reaction
Explanation
When benzene is heated in air with V2O5 at 450°C, it undergoes oxidation to form maleic anhydride. This reaction is an example of a free radical oxidation reaction. The V2O5 catalyst provides the free radicals that initiate the reaction. The free radicals then react with the benzene molecules, forming a variety of intermediate products, which eventually rearrange and react to form maleic anhydride.The other options are incorrect because benzene does not undergo substitution, addition, or elimination reactions under these specific conditions.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
