O638: Identification of Phenols – Ferric Chloride Test

WebThe test for phenolic group is a qualitative test used to determine the presence of a phenolic group in a molecule. The test uses a reagent, usually ferric chloride, to convert any phenols in the molecule into phenolates. These phenolates will then form a violet color with the addition of a second reagent, usually potassium iodide. Web2. júl 2013 · Aluminum Chloride D D D D C B A B A A A A A C - A A D A A A A A A B.
