Question

The analgesic Tylenol is often taken by people who are allergic to aspirin. Tylenol contains acetaminophen (structure shown) as the active ingredient. Is the structure of acetaminophen similar to the structure of aspirin? In what way? Would acetaminophen give a positive phenol test? What products would be obtained if acetaminophen were hydrolyzed in acidic aqueous solution?
