Q. In which of the following the number of carbon atoms does not remain same when carboxylic acid is obtained by oxidation?

AIPMTAIPMT 1992Aldehydes Ketones and Carboxylic Acids

Solution:

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.
