Q1. A student performs a Benedict's test on several carbohydrate samples. Which disaccharide will fail to produce a brick-red precipitate despite being a sugar?
Answer: Sucrose
Explanation: Sucrose is a non-reducing sugar because its glycosidic bond involves both anomeric carbons. Glucose is tempting because it is a common sugar, but it is reducing.
