Silver Mirror with Tollens Reagent is formed by
Correct answer: C. Aldehydes
- A. Acid halides
- B. Alcohols
- C. Aldehydes
- D. Ketones
Explanation
Tollens' reagent, also known as the silver mirror test, is a chemical test used to detect the presence of aldehydes. When an aldehyde is treated with Tollens' reagent (a solution of silver nitrate and ammonia), a silver mirror is formed on the inner surface of the test tube. This is due to the reduction of silver ions by the aldehyde, resulting in the formation of metallic silver.

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.
