Explanation:
Acetone and acetaldehyde can be identified by Schiffs test due to their ability to react with Schiff's reagent.
Schiffs Test:
Schiffs test is a chemical test used to detect the presence of aldehydes in a given sample. This test involves the reaction of aldehydes with Schiff's reagent, which is a solution of fuchsine dye and sulfur dioxide in acidic medium.
Acetone and Acetaldehyde Identification:
- Acetone and acetaldehyde are both aldehydes and can react with Schiff's reagent to form a colored product.
- The formation of a pink or magenta color indicates a positive result for the presence of acetone or acetaldehyde in the sample.
Other Options:
- Molisch test is used to detect the presence of carbohydrates in a sample.
- Bromoform test is used to detect the presence of methyl ketones like acetophenone.
- Iodoform test is used to detect the presence of compounds containing a methyl ketone functional group.
Therefore, the correct test for identifying acetone and acetaldehyde is the Schiffs test due to their reactivity with Schiff's reagent.
