Identify a medicinal compound having amide linkage.

Step-by-step solution

Analysis of medicinal compounds with amide linkages: Aspirin ( CH₃COOC₆ H₄ COOH ) contains ester and carboxylic acid functional groups without amide functionality. Methylsalicylate ( HOC₆ H₄ COOCH₃ ) features ester and phenolic hydroxyl groups, lacking an amide linkage. Curcumin contains diketone and phenolic groups in its diarylheptanoid structure but no amide group. Paracetamol ( HOC₆ H₄ NHCOCH₃ ), chemically N-(4-hydroxyphenyl)acetamide, contains the characteristic amide linkage ( - NHCO ^- ). Only paracetamol p
