1. Place 2.2 g of 4-aminophenol and 5 mL of distilled water in a 25 mL conical flask. A magnetic stirring bar is added to the flask. 2. Heat the mixture under stirring to 80 Â°C in a water bath. 3. Add slowly 2.5 mL of acetic anhydride with a Pasteur pipette to the mixture. Let the mixture react for 10 minutes. Why do we add the acetic anhydride slowly in step 3? Identify which functional groups would participate in the unwanted reaction (not the paracetamol reaction) and if you can, what type of reaction it is.
