Question

Layer's test is used for what purpose?

• A. To detect aldehydes
• B. To detect ketones
• C. To detect carboxylic acids
• D. To detect aromatic amines

Hint:

Layer's test is a simple method for detecting aldehydes based on the formation of a yellow precipitate.

Answer 1

The Correct Option is A

Layer’s test is a qualitative test used to detect aldehydes, based on the formation of a characteristic yellow precipitate when an aldehyde reacts with a reagent.

1. Step 1: Understand Layer's test. - In Layer's test, an aldehyde is reacted with a specific reagent, resulting in the formation of a yellow precipitate. - This test is commonly used to distinguish aldehydes from other functional groups. Thus, Layer's test is used to detect aldehydes.
