Question

distinguish between acetaldehyde and acetanone​

Answer 1

Explanation:

Acetaldehyde and acetone can be distinguished because acetaldehyde is an aldehyde and acetone is a ketone. Aldehydess and ketones show different reactions with same reagents because there is a difference in their structure. Both acetaldehyde and acetone are colourless liquids at room temperature.

Answer 2

Answer:

Acetaldehyde and acetone have differences when they react with some compounds. Note that, acetaldehyde can be oxidized easily to acetic acid. But acetone cannot be oxidized easily like acetaldehyde. We use this characteristic to identify acetaldehyde and acetone.

Acidic potassium permanganate (H+ / KMnO4) solution is added to acetaldehyde and acetone separately to see, what will be oxidized. When oxidation reduction reaction occur, purple colour of H+ / KMnO4 is changed to colourless or light pink.
