Which of the following compounds will react with Tollens reagent to give metallic silver?
Correct answer: A. Methanal
- A. Methanal
- B. Acetic acid
- C. Ethyl alcohol
- D. Acetore
Explanation
Methanal is an aldehyde that can undergo oxidation with Tollen's reagent to produce metallic silver. The rest of the compounds won't react with Tollen's reagent so option A 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.
