Which of the following compounds shows Silver mirror test ?
Which of the following compounds shows Silver mirror test ?
Show Hint
Tollens' reagent is reduced by aldehydes, so acetaldehyde gives the silver mirror.
Updated On: Nov 12, 2026
- Acetone
- Acetaldehyde
- Ethanol
- Benzophenone
Show Solution
The Correct Option is B
Solution and Explanation
Step 1: Recall the rule
Aldehydes are easily oxidised and act as reducing agents, while ketones are not oxidised by mild reagents.
Step 2: Pick the aldehyde
Only acetaldehyde is an aldehyde among the options, so it gives the silver mirror.
Step 3: Match the option
The option naming acetaldehyde matches.
Final Answer:
Only the aldehyde reduces Tollens' reagent to silver. \[ \boxed{\text{(B) }\text{Acetaldehyde}} \]
