What is the IUPAC name for the compound CH₃CH(CH₃)COCH₃?
Correct answer: B. 3-Methyl-2-butanone
- A. 2-Methyl-3-butanone
- B. 3-Methyl-2-butanone
- C. Isobutyl methyl ketone
- D. 2-Pentanone
Explanation
The longest carbon chain containing the ketone is a four carbon compound (butanone). Numbering from the right side gives the carbonyl group the lowest possible number (2). A methyl group is attached to carbon 3, so the name is 3- methyl-2-butanone.

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.
