Can someone help me deduce the oxydation numbers? This is the answer : In this reaction, the oxidation number of the carbon atom bonded to the oxygen changes from 1 in propanal to 3 in propanoic acid. Propanal is therefore oxidized to propanoic acid. The KMnO4 is reduced in this reaction. But I got +2 for the oxydation number of the carbon in the ractants and +4 for the carbon in the products... please help!
