Vedclass · Answer

(B) The reaction of an alkene with cold and dilute alkaline $KMnO_4$ (also known as Baeyer's reagent) is an oxidation reaction. In this reaction,the double bond of the alkene is cleaved,and two hydroxyl $(-OH)$ groups are added to the adjacent carbon atoms,resulting in the formation of a vicinal diol,commonly known as a glycol. For example,ethene $(CH_2=CH_2)$ reacts with cold dilute alkaline $KMnO_4$ to form ethane$-1,2-$diol $(HO-CH_2-CH_2-OH)$.
