Abstract: The oxidation of alkylbenzenes to benzoic acid using acidic potassium permanganate is a fundamental topic in introductory organic chemistry. Nevertheless, this reaction mechanism is rarely introduced in organic chemistry textbooks, both domestically and internationally, which often leads to confusion among students. Drawing on relevant experimental findings from the literature, this article delineates reasonable mechanisms for this transformation. It is anticipated that this discussion will enhance students’ comprehension of the reaction and serve as a valuable supplement to organic chemistry instruction.
