Which reagent is used to distinguish between aldehydes and ketones?
Correct Answer: Tollens' reagent
- Step 1: Understand that aldehydes and ketones are both types of organic compounds.
- Step 2: Know that aldehydes have a specific functional group (-CHO) at the end of the carbon chain.
- Step 3: Recognize that ketones have a functional group (C=O) in the middle of the carbon chain.
- Step 4: Learn that certain reagents can react differently with aldehydes and ketones.
- Step 5: Identify common reagents used to distinguish between them, such as Tollens' reagent, Fehling's solution, and Benedict's solution.
- Step 6: Remember that aldehydes can reduce these reagents, causing a visible change (like a color change), while ketones do not.
