Vedclass · Answer

(A) $Baeyer's$ reagent is an alkaline solution of potassium permanganate $(KMnO_4)$.It is used in the laboratory to test for the presence of unsaturation (double or triple bonds) in organic compounds.When an alkene reacts with $Baeyer's$ reagent,the purple color of $KMnO_4$ disappears,and a brown precipitate of manganese dioxide $(MnO_2)$ is formed,indicating the presence of a double bond.
