The correct Answer is:
To solve the matching question, we will analyze each component in Column I and match it with the appropriate component in Column II based on the properties of the carbohydrates listed. ### Step-by-Step Solution: 1. **Match Sucrose (A)**: - Sucrose is a disaccharide composed of glucose and fructose. - It does not have a free aldehyde group, which means it does not form a hemiacetal. - Therefore, the correct match is: - **A → P (Two acetals)** - **A → Q (No hemiacetal)** (This is also correct since sucrose does not have a hemiacetal.) 2. **Match Maltose (B)**: - Maltose is also a disaccharide made up of two glucose units. - It has a free aldehyde group, which allows it to form a hemiacetal. - The glycosidic bond in maltose is a **beta-1,4 glycosidic bond**. - Hydrolysis of maltose yields two glucose molecules. - Therefore, the correct matches are: - **B → Q (No hemiacetal)** (This is incorrect since maltose does have a hemiacetal.) - **B → R (Beta-1,4-glycosidic bond)** - **B → S (Hydrolysis product is glucose)** 3. **Match Lactose (C)**: - Lactose is a disaccharide composed of glucose and galactose. - It has a hemiacetal structure due to the presence of a free aldehyde group. - The glycosidic bond in lactose is also a **beta-1,4 glycosidic bond**. - Hydrolysis of lactose yields glucose and galactose. - Therefore, the correct matches are: - **C → P (Two acetals)** (This is incorrect since lactose has a hemiacetal.) - **C → R (Beta-1,4-glycosidic bond)** - **C → S (Hydrolysis product is glucose)** 4. **Match Cellulose (D)**: - Cellulose is a polysaccharide made up of many glucose units. - It does not have free aldehyde groups, so it does not form hemiacetals. - The glycosidic bond in cellulose is a **beta-1,4 glycosidic bond**. - Hydrolysis of cellulose yields glucose. - Therefore, the correct matches are: - **D → P (Two acetals)** (This is incorrect since cellulose does not have acetals.) - **D → Q (No hemiacetal)** - **D → R (Beta-1,4-glycosidic bond)** - **D → S (Hydrolysis product is glucose)** ### Final Matches: - **A → P, Q** - **B → R, S** - **C → R, S** - **D → Q, R, S**
