WebApr 7, 2024 · Phenol Test. A ferric chloride solution is a test for phenols, as they form intensely colored complexes with \(\ce{Fe^{3+}}\) (often dark blue). The actual structure of these complexes is debated,\(^{15}\) but may be of the general form in Figure 6.69. Some carbonyl compounds with high enol content can give false positives with this test. Web4. Iron(III) Chloride Test. Addition of iron(III) chloride dissolved in chloroform (trichloromethane) to a phenol dissolved in chloroform, gives a colored solution upon addition of pyridine. Depending on the structure of the phenol the color of the product can be most anything from red to violet. Alcohols do not give this test. designer of nbc peacock
