Baeyer’s Reagent: Definition, Preparation, and Reaction
WEBBaeyer’s reagent is an alkaline solution of cold potassium permanganate (KMnO 4). It is a potent oxidizing agent and is used in qualitative organic analysis to test for the presence of unsaturation.

WEBAlkaline potassium permanganate test (Baeyer’s test): In this test the pink colour potassium permanganate disappears when an alkaline potassium permanganate is added to an unsaturated hydrocarbon. The disappearance of pink colour may take place with or without the formation of brown precipitate of manganese oxide.

WEBPermanganate (Baeyer) Test. A potassium permanganate \(\left( \ce{KMnO_4} \right)\) solution is a test for unsaturation (alkenes and alkynes) or functional groups that can be oxidized (aldehydes and some alcohols, Figure 6.66).
Baeyers Test - Labster
WEBThe baeyers test is used to test for an unsaturated carbon carbon bond, such as an alkene or alkyne, but not an aromatic carbon carbon bond. Potassium permanganate (KMnO4) solution is a purple color. When potassium permanganate reacts with an alkene the solution changes from a purple color to a brown color, and a glycol is formed.
Potassium permanganate - Wikipedia
WEBKMnO 4 is used in qualitative organic analysis to test for the presence of unsaturation. It is sometimes referred to as Baeyer's reagent after the German organic chemist Adolf von Baeyer. The reagent is an alkaline solution of potassium permanganate.
Baeyer's Reagent: Test, Preparation, Properties - ProtonsTalk
WEBBaeyer’s test is a laboratory test used to determine the presence of a double bond in an unsaturated compound. In this reaction, an unsaturated compound with double bonds reacts with cold and dilutes alkaline potassium permanganate to form vicinal glycols, also known as 1,2-diols.
Baeyer s Test | Physics Van | Illinois
WEBThe Baeyer test for unsaturation is for determining the presence of carbon-carbon double bonded compounds, called alkenes or carbon-carbon trible bonded compounds, called alkyne bonds. The Baeyer test uses dilute Pottasium Permanganate to Oxidize the carbon-carbon double or triple bond.

WEBPermanganate Test for Unsaturation (Baeyer Test): Aqueous permanganate rapidly oxidizes double and triple bonds while being reduced to MnO2, a brown precipitate. Therefore, disappearance of the purple color and formation of a brown precipitate in minutes is a positive test.
Baeyer test - Oxford Reference
WEBQuick Reference. A test for unsaturated compounds in which potassium permanganate is used. Alkenes, for example, are oxidised to glycols, and the permanganate loses its colour:3R 2 C=CR 2 +2KMnO 4 +4H 2 O → 2MnO 2 +2KOH+3R 2 COHR 2 COH.
