Which of the following compounds is present in camphor and menthone?
Correct answer: D. Ketones
- A. Aldehyde
- B. Alcohol
- C. Esters
- D. Ketones
Explanation
Both camphor and menthone are ketones. Ketones have a carbonyl group (C=O) in the middle of a carbon chain. In camphor, the carbonyl group is part of a fused ring system, and in menthone, it is part of an open-chain structure. Therefore, option d is correct.

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.
