Q: Which reagent is commonly used to distinguish between aldehydes and ketones?
Solution: All of the mentioned reagents can be used to distinguish between aldehydes and ketones, as aldehydes can be oxidized while ketones cannot.
Steps: 7
Step 1: Understand that aldehydes and ketones are both types of organic compounds.
Step 2: Know that aldehydes have a functional group (-CHO) at the end of the carbon chain.
Step 3: Know that ketones have a functional group (C=O) in the middle of the carbon chain.
Step 4: Learn that aldehydes can be oxidized, meaning they can react with certain chemicals to form acids.
Step 5: Recognize that ketones cannot be easily oxidized like aldehydes.
Step 6: Identify that reagents like Tollen's reagent or Fehling's solution can be used to test for oxidation.
Step 7: Conclude that if a reagent causes a reaction (like a color change) with a compound, it is likely an aldehyde, while no reaction indicates a ketone.
