Ketones are not easily oxidised. However, under drastic conditions or with powerful oxidising agents such as conc. HNO 3, KMnO 4 / H 2 SO 4 or K 2 Cr 2 O 7 / H 2 SO 4, cleavage of carbon-carbon bond takes place giving a mixture of carboxylic acids having less number of carbon atoms than the original ketone.
