How do you test for phenols?

Phenols can be tested using several methods, one common approach being the use of Ferric Chloride (FeCl3) solution. When a phenolic compound is added to this solution, a color change occurs, typically resulting in a purple or violet color, indicating the presence of phenols. Another method involves the use of bromine water, where phenols will decolorize the solution due to the formation of brominated derivatives. Additionally, the pH test can help differentiate phenols from other alcohols, as phenols typically exhibit acidic properties.
