During oxidation of unsymmetrical ketones which atom is oxidized?
Correct answer: B. Carbon attached to smaller number of hydrogen atom
- A. Carbonyl carbon
- B. Carbon attached to smaller number of hydrogen atom
- C. Carbon attach to larger number of hydrogen atoms
- D. Hydrogen
Explanation
The oxidation of unsymmetrical ketones involves the cleavage of the carbon-carbon bond adjacent to the carbonyl group. The carbon atom that is attached to fewer hydrogen atoms is more electron deficient and therefore more susceptible to oxidation. This carbon atom is oxidized, and the other carbon atom is reduced. The result is the formation of two different carboxylic acids.

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.
