"WebKetone oxidation implies the rupture of a C-C bond. If it is energic (KMnO4, K2Cr2O7) two carboxylic groups will be produced. If it is smooth (Baeyer-Villiger oxidation), an ester is produced that, once it is hydrolized, gives rise to a carboxylic acid and an alcohol. " - Ketone carboxylic acid reaction
