Benedict’s reagent is used for detecting reducing sugars because
Select one:
a. a reduction of the sugar occurs producing an acid.
b. the aldehyde group in the sugar is oxidized.
c. the copper ion in the reagent is oxidized as the sugar is reduced.
d. the —OH groups are exchanged for hydrogens.View
Answer
c. the copper ion in the reagent is oxidized as the sugar is reduced.Explanation
what happens is that the copper (II) ions in Benedict’s solution are reduced to Copper (I) ions, which causes the colour change bearing i mind that each of the sugars do have mainly each contains a glucose with a free reducing aldehyde moiety. this when heated together, the solution changes its colour to orange-red/ brick red.
