Which of the following is produced by the action of CH3CI on benzene in presence of AICI3 followed by oxidation with acidified KMnO4 ?
Correct answer: D. Benzoic acid
- A. Toluene
- B. o-Xylene
- C. m-Xylene
- D. Benzoic acid
Explanation
The first step is a Friedel-Crafts alkylation, which produces toluene. The second step is the strong oxidation of the alkyl side chain of toluene. Acidified KMnO4 will oxidize the methyl group of toluene all the way to a carboxylic acid group, forming benzoic acid.

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.
