Which one of the following set of compounds oxidize aldehydes as well as ketones
Correct answer: D. K2Cr2O7 + Conc. H2SO4
- A. CuSO4 + NaOH + Citric acid
- B. AgNO3 + NH4OH
- C. CuSO4 + NaOH + Tartaric acid
- D. K2Cr2O7 + Conc. H2SO4
Explanation
A, B, C are weak oxidizing agent, so they can oxidize aldehydes only (due to high reactivity than ketone) but not ketones but the combination of K2Cr2O7 and H2SO4 produces nascent oxygen which is very strong oxidizing agent. So, it can oxidize both aldehydes and ketone.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
