RankGuru · Accepted Answer

**Benedict's Test** is used to detect **Reducing Sugars**.
- Reducing sugars have a free (or potentially free) aldehyde or ketone group that can reduce $Cu^{2+}$ (blue complex) to $Cu_2O$ (brick-red precipitate).
- **Glucose**, being an aldose, is a strong reducing sugar and gives a positive result.
- **Sucrose** is non-reducing because its functional groups are tied up in the glycosidic bond.
- Polysaccharides like **Starch** and **Cellulose** do not give a significant positive result because they lack a sufficient number of free hemiacetals.
