What Is Fecl3 Test Phenol Confirmatory Test Of Phenol This video channel is developed by amrita university's create amrita.edu create for more information @ amrita.olabs.co.in ?sub=73&brch=8&sim. Phenol (also called carbolic acid) is an aromatic organic compound with the molecular formula c 6 h 5 oh. it is a white crystalline solid that is volatile. the molecule consists of a phenyl group (−c 6 h 5) bonded to a hydroxy group (−oh). mildly acidic, it requires careful handling because it can cause chemical burns. Add 1ml of phenol to the sodium nitrite solution. heat the mixture gently and allow it to cool. add 1ml of concentrated sulfuric acid to it and shake the contents. observe the change in the colour of the solution. dilute the solution with water so that the given compound turns red if a phenolic group is present. This reaction can be used as a test for phenol groups. equations 3aroh fecl3 → fe(oar)3 3hcl. to conduct demonstration: mix several drops or a few crystals of compound to be tested in a beaker or in a 200mm test tube. add a few drops of 1% fecl3. as a control, add a few drops of 1% fecl3 to water in a second beaker.

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. To 10 drops of solution, add 6 m nh3(aq) nh 3 ( aq) until neutral. make the solution acidic by adding one or more drops of 6 m hcl hcl. add 1 ml of thioacetamide and stir well. heat the test tube in the boiling water bath for 5 minutes. if antimony is present, a red orange precipitate of antimony sulfide should form.
