Carbonyl compounds give different oxidation products withdifferent reagents. Several oxidising agents can be used to oxides carbonyl compound. Ammonical silvernitrate (Tollens' reagent) oxidises aliphitic as well as aromatic aldehydes. R-CHOoverset("Tollenes reagent ")rarrR-COOH+Ag("Silver mirror") Strong oxidising agents like KMnO_(4)//H^(+),HNO_(3) K_(2)Cr_(2)O_(7)//H^(+) oxidise aldehydes as well as ketones. Open chain ketnoes on oxidation give mixture of two carboxylic acids. Oxidation of unsymmetrical ketones takes place acording to Popoff's rule. According to this rule, alpha whose bond breks in oxidation always belongs to thealkyl group which has more number of carbons. 2-Methylcycolhexanone on oxidation will give :
