Question: Which of the following is a method to distinguish between aldehydes and ketones?

Options:

Correct Answer: Tollens\' test

Solution:

Tollens\' test can be used to distinguish between aldehydes and ketones, as aldehydes reduce Tollens\' reagent.

Which of the following is a method to distinguish between aldehydes and ketones?

Which of the following is a method to distinguish between aldehydes and ketones?

Step 1: Understand that aldehydes and ketones are both types of organic compounds called carbonyls, but they have different structures.
Step 2: Know that aldehydes have a carbonyl group (C=O) at the end of the carbon chain, while ketones have it in the middle.
Step 3: Learn about Tollens' reagent, which is a special chemical solution used in tests.
Step 4: Remember that when you add Tollens' reagent to an aldehyde, it will change color or form a silver mirror, indicating a positive result.
Step 5: Understand that ketones do not react with Tollens' reagent, so there will be no color change or silver mirror.
Step 6: Conclude that if the solution changes color or forms a silver mirror, you have an aldehyde; if it does not, you have a ketone.
