Question

Quizplus · Accepted Answer

A reducing sugar is a carbohydrate that has a free aldehyde or ketone group that can react with an oxidizing agent, such as Cu+2. Therefore, Option B) reducing is the correct answer. Option A) oxidizing is incorrect as it refers to the reactant, not the sugar. Option C) rentose and D) aldose are types of monosaccharides and do not describe the capacity of a sugar to react with oxidizing agents.
