Vedclass · Answer

(B) The test for unsaturation in alkenes is known as the Baeyer's test.In this test,alkenes react with cold dilute alkaline $KMnO_4$ solution (Baeyer's reagent).The purple/pink colour of the $KMnO_4$ solution disappears,and a brown precipitate of $MnO_2$ is formed,indicating the presence of a double bond (unsaturation).Therefore,cold dilute alkaline $KMnO_4$ is the correct reagent.

Which one of the following reagents is used for the detection of unsaturation in alkenes?
