Question

Identify a medicinal compound having amide linkage.

• A. Aspirin
• B. Methylsalicylate
• C. Curcumin
• D. Paracetamol

Hint:

Look for "aceta" or "mide" in the chemical names! Paracetamol is chemically known as Acetaminophen, an abbreviation of para-acetylaminophenol. The acetyl-amino part forms the amide link.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
An amide linkage consists of a carbonyl group bonded to a nitrogen atom ($-NH-CO-$).

Step 2: Formula Application:
Structure of Paracetamol: 4-Acetamidophenol.

Step 3: Explanation:
Paracetamol contains an acetyl group attached to the nitrogen of an aniline derivative ($CH_3-CO-NH-C_6H_4-OH$). Aspirin and Methylsalicylate contain ester linkages, not amide linkages.

Step 4: Final Answer:
Paracetamol is the compound with an amide linkage.
