Question

TestHub · Accepted Answer

Question Explanation: The question asks which given compounds can give a positive Silver Mirror (Tollens’) test.

Concept: This question is based on Tollens’ test.

Solution: The Silver Mirror test is given by aldehydes due to the oxidation of the –CHO group to a carboxylate ion, reducing Ag⁺ to metallic silver. Formaldehyde (HCHO) and acetaldehyde (CH₃CHO) are aldehydes and give a positive test. Benzophenone and acetone are ketones and do not respond.

$R — C H O + 2 [A g (N H_{3})_{2}]^{+} + 3 O H^{-} ⟶ R — CO O^{-} + 2 A g ↓ + 4 N H_{3} + 2 H_{2} O$

Final Answer: Option (A & C)
