What functional groups must be present for a positive Salicylate Test?

The positive Salicylate Test requires the presence of both carboxylic acid and phenolic groups. The test is specifically designed to detect salicylates, which are compounds that contain a carboxylic acid group (-COOH) attached to a phenolic compound, characterized by a hydroxyl group (-OH) directly bonded to an aromatic ring.

In the context of salicylate, the carboxylic acid moiety is critical because it participates in the reaction that produces a colored complex during the test, which indicates a positive result. The phenolic group enhances the reactivity of these compounds and contributes to the overall structure and function of salicylates, allowing for their detection through this test.

While other options list groups that may be relevant in different contexts or tests, they lack the specific combination of carboxylic acid and phenolic groups necessary for the Salicylate Test to yield a positive outcome.
