Aldehydes can be oxidized by _.
Correct answer: D. All of these
- A. K2Cr2O7
- B. HNO3
- C. Tollen's reagent
- D. All of these
Explanation
Aldehyhdes have the general formula of CnH2n+2CHO. It is to be kept in mind that all aldhyde have CHO group at the terminal carbon. Since aldehyde always have one -H attached, thus there is least stearic hindrance in comparison to ketones and as a result, Aldhydes can be oxidised by both mild and strong oxidising agents mentioned in the options. According to the explanation above, 'All of these' is the correct option.

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.
