If a small amount of br2 is added to an aqueous solution of an unknown monosaccharide, the reddish-brown color of br2 will disappear if the monosaccharide is _____.

Respuesta :

Answer:
            If a small amount of br2 is added to an aqueous solution of an unknown monosaccharide, the reddish-brown color of br2 will disappear if the monosaccharide is an Aldose.

Explanation:
                  This happens because the Aldose contains a carbonyl group called Alsedyde. Bromine being a oxidizing agent oxidizes the aldehyde functional group to Carboxylic Acid moiety. While this test is not positive in case of Ketonic Functional group.
