Final answer:
Acetaminophen's lewis structure has a total of four lone pairs.
Step-by-step explanation:
The Lewis structure and three-dimensional model of acetaminophen consist of the arrangement of atoms and their bonding in the molecule. In this case, acetaminophen has the structure designated as AX3E, with three bonding pairs and one lone pair. Assuming each atom has enough non-bonding lone pairs to ensure neutral formal charge and satisfaction of the octet rule at each atom, there are a total of four lone pairs in the structure.
