Benzoic acid is the only oxidation product along with formation H2O and CO2, of an organic compound A, when A is treated with acidified potassium dichromate, A is
Correct answer: A. Ethyl benzene
- A. Ethyl benzene
- B. Benzoyl halide
- C. Aniline
- D. Benzophenone
Explanation
When Ethyl benzene is treated with acidified potassium dichromate, the side chain (ethyl group) is oxidized to a carboxylic acid group (-COOH), forming benzoic acid. This is because the strong oxidizing agent fully oxidizes the alkyl side chain to the carboxylic acid. None of the other options, including Benzoyl halide, Aniline, and Benzophenone, undergo oxidation to form benzoic acid under these conditions. Benzoyl halide might undergo hydrolysis, Aniline oxidizes differently due to its amino group, and Benzophenone is resistant to oxidation as it is already a ketone.

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.
