What product forms when the compound below is treated with Benedict's reagent?

Question

Quizplus · Accepted Answer

The compound given in the image is a reducing sugar as it has a free aldehyde functional group. Benedict's reagent is used to detect reducing sugars. When a reducing sugar is added to Benedict's reagent and heated, it reduces the Cu2+ ions present in the reagent to Cu+ ions, which results in a color change. The intensity of the color is directly proportional to the amount of reducing sugar present in the sample. The color changes from blue to green, yellow, orange, and finally, brick red (indicating a high concentration of reducing sugar). 
Option C has the highest concentration of reducing sugar among the given options, and it will produce a brick red color with Benedict's reagent. The other options have lower concentrations of reducing sugar, and the resulting colors with Benedict's reagent will be in the green to yellow range.
