Which of the following compounds is a ketone?
- A. CH3CHO
- B. CH3COCH3
- C. CH3COOH
- D. CH3CH2OH
Explanation
In propanone the carbonyl group lies between two carbon atoms, which is the defining feature of a ketone, while CH3CHO is the aldehyde ethanal with the carbonyl at the end of the chain. CH3COOH is a carboxylic acid, whose carbonyl carbon also carries a hydroxyl group, and CH3CH2OH is an alcohol. Reading which atoms flank the carbonyl carbon is the whole test.
