Overview
Acetaminophen (Tylenol) has three functional groups. It's a great example of how functional groups determine a drug's properties.
Aromatic Ring
The aromatic ring forms the core structure. The hydroxyl (-OH) and amide (-CONH-) are on opposite sides of the ring (para position).
Hydroxyl (-OH)
The amide group (-CONH-) has a nitrogen bonded to both a C=O and the ring. It's different from an amine (-NH₂) because the nitrogen is bonded to a carbonyl carbon. The hydroxyl (-OH) makes the molecule more water-soluble.
Complete Analysis
All three groups: aromatic ring, hydroxyl (-OH), and amide (-CONH-). The amide is the key pharmacological group - not an amine!
