The Baeyer test for unsaturated hydrocarbons involves reaction with a hydrocarbon with alkene (or alkyne) like double bonds. Even though you can draw double bonds for aromatic hydrocarbons (benzene or toluene), these double bonds do not react like alkene double bonds. Evidence that an alkene-like double bound is present is the rapid .Figure 6.38: Results of two aldehydes in the bromine test (left tube is isobutylaldehyde and right tube is benzaldehyde). 6.4A: Overview of Chemical Tests. A chemical test is typically a fast reaction performed in a test tube that gives a dramatic visual clue (a color change, precipitate, or gas formation) as evidence for a chemical reaction.permanganate tests for unsaturationFigure 6.38: Results of two aldehydes in the bromine test (left tube is isobutylaldehyde and right tube is benzaldehyde). 6.4A: Overview of Chemical Tests. A chemical test is typically a fast reaction performed in a test tube that gives a dramatic visual clue (a color change, precipitate, or gas formation) as evidence for a chemical reaction. 2. Alkaline KMnO, 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. ProcedureThe Baeyer test is a qualitative test used to test for the presence of unsaturation. To perform the Baeyer test, cold alkaline potassium permanganate solution, which is purple in color, is added to an unidentified chemical substance. The potassium permanganate acts as an oxidizing agent during this test.

The Baeyer test is used less frequently than the bromination test to determine if a compound is an alkene because the Baeyer solution can react with other functional groups on the molecule as well as any alkene groups and be decolorized. The following reaction equation shows how ethene molecules can be reacted with cold, dilute, alkaline .

A chemical test is typically a fast reaction performed in a test tube that gives a dramatic visual clue (a color change, precipitate, or gas formation) as evidence for a chemical reaction. For example, addition of an orange chromic acid reagent to some compounds causes the chromium reagent to change to a blue-green color (Figure 6.37a).

KMnO 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. Reaction with double or triple bonds (-C=C- or -C≡C-) causes the color to fade from purplish .baeyer test 1.
