Directions: Reference the worksheet entitled PRACTICE: Lewis Structures. Assign the electron pair geometry, molecular geometry, hybridization, and bond
angle with respect to the central atom(s). Also, determine if the molecule is polar or nonpolar, and indicate the predominant type of intermolecular force
exhibited by the molecule.
