Which of the following is the correct IUPAC name of acetone?
Correct answer: A. 2-Propanone
- A. 2-Propanone
- B. 3-Propanone
- C. 2-Butanone
- D. 2-Pentanone
Explanation
Acetone has the structure CH₃-CO-CH₃, a three-carbon ketone. The carbonyl group is on the second carbon, so the IUPAC name is 2-propanone. Other options either have wrong chain length or wrong carbon numbering.

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.
