All of the following statements about oxidation of carbonyls are true except .a. Tollens' test involves reduction of Ag⁺. b. oxidation of aldehydes produces carboxylic acids. c. oxidation of ketones produces esters. d. Benedict's test involves reduction of Cu²⁺.

C

Explanation:

Amongst the options in the question, the option that ketones oxidizes to esters is wrong.

Aldehydes and ketones belong to a group of organic compounds called the carbonyls. Both are functional group isomers and are characterized by the bond C=O

When ketones or alkanones are oxidized, there are series of products which are formed. For the ketones, the highest or end point of their oxidation is the carboxylic or alkanoic acid and not the esters.
