Consider the following Reaction CH3COOH +4[O] in presence of K2Cr2O7.conc.H2SO4of the following, which product is formed?
Correct answer: D. Reaction is not possible
- A. CH3OH
- B. CH3COOH+HCOOH
- C. CH3-CH2-OH
- D. Reaction is not possible
Explanation
While K2Cr2O7 in concentrated H2SO4 is a strong oxidizing agent, the presence of a pre-existing carboxylic acid group (CH3COOH) in the substrate makes further oxidation unlikely under these conditions.Acetic acid, the starting material, has already reached its highest oxidation state with a carboxylic acid group. Further oxidation would require breaking strong carbon-oxygen bonds, which is energetically unfavorable and not readily achieved with this specific reagent combination.Therefore, although the oxidizing agent and acid are present, they don't react with acetic acid in this specific manner.

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.
