Which of the following can be used for the oxidative preparation of aldehydes from alcohols:
Correct answer: D. All of these
- A. Pt-asbestos
- B. FeO and Mo2O3
- C. Na2Cr2O7 and H2SO4
- D. All of these
Explanation
FeO, MO2O3 and Pt-asbestos are catalysts used for air oxidation of alcohols to aldehydes while Na2Cr2O7+H2SO4 combination is used for the production of nascent oxygen which is used to oxidize alcohols to carbonyl compounds.

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.
