The weakest oxidizing agent that can be used in the oxidation of aldehyde reaction:
Correct answer: D. AgNO3/NH4OH
- A. K2Cr2O7H2SO4
- B. Na2Cr2O7/H2SO4
- C. KMnO4/H2SO4
- D. AgNO3/NH4OH
Explanation
Option D is correct.AgNO3/NH4OH is the weakest oxidizing agent that can be used in the oxidation of carboxylic acids. The oxidation of aldehyde is a chemical reaction in which a aldehyde is converted to another compound by the addition of oxygen. The oxidizing agent is the substance that provides the oxygen. AgNO3/NH4OH is a mild oxidizing agent. It is not strong enough to oxidize carboxylic acids to carbon dioxide. However, it is strong enough to oxidize aldehydes to carboxylic acid. Here is the reaction of the oxidation of carboxylic acids with AgNO3/NH4OH: R-CHO + 2AgNO3 + 3NH4OH → R-COOH + 2Ag + 2NH4NO3 + H2O

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
