Which oxidizing agent is used in oxidation of Aldehydes into carboxylic acids?
Correct answer: D. Both A and B
- A. Acidified KMnO4
- B. Acidified K2Cr2O7
- C. Ag2O
- D. Both A and B
Explanation
The correct answer is Both A and B because both acidified KMnO4 and acidified K2Cr2O7 are strong oxidizing agents capable of oxidizing aldehydes to carboxylic acids. Acidified KMnO4 is commonly used in organic synthesis due to its effectiveness and availability. Acidified K2Cr2O7, another strong oxidizing agent, is also effective in achieving this transformation. On the other hand, Ag2O is not suitable for this particular oxidation reaction, which is why it is incorrect.

About Reactivity of Aldehydes and Ketones
The polar carbonyl group makes aldehydes and ketones undergo nucleophilic addition, reduction and condensation reactions. Aldehydes are generally more reactive and oxidise readily to carboxylic acids, whereas ketones resist mild oxidation; reactions with hydrogen cyanide, sodium bisulfite and 2,4-DNP help identify their behaviour.
