Which is mismatched regarding the structure ?

Options

A.
B.
C.
D. Both (2) & (3)

Answer

To determine which structure is mismatched with its name, we will analyze each option step by step.

### Step 1: Analyze the first option - Sulphanilamide
- **Structure**: The structure consists of a benzene ring with an NH2 group (amino group) and a sulfonyl group (SO2).
- **Correctness**: The structure matches the name sulphanilamide, which is correctly matched.

### Step 2: Analyze the second option - Aspirin
- **Structure**: The structure presented has a benzene ring with various functional groups, including a carboxylic acid (COOH) and an ester (OCOCH3).
- **Correctness**: The structure does not accurately represent aspirin. Aspirin, or acetylsalicylic acid, has a specific structure that includes an acetyl group and a carboxylic acid, which is not depicted correctly here. Therefore, this is incorrectly matched.

### Step 3: Analyze the third option - Paracetamol
- **Structure**: The structure consists of a benzene ring with an OH (hydroxyl group) and an NH2 (amino group).
- **Correctness**: This structure matches the name paracetamol, which is correctly matched.

### Conclusion
Based on the analysis:
- The first option (Sulphanilamide) is correctly matched.
- The second option (Aspirin) is incorrectly matched.
- The third option (Paracetamol) is correctly matched.

Thus, the answer to the question is that the mismatched structure is **Aspirin**.
