Which of the following does not give iodoform test?
Correct answer: D. Benzophenone
- A. Ethanol
- B. Ethanal
- C. Acetophenone
- D. Benzophenone
Explanation
The reaction of iodine and base with methyl ketones is called the "iodoform test". It is used to probe the presence of a methyl ketone. However, Benzenophenone is a phenyl ketone and does not contain this group giving a negative test.

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.
