Draw a Lewis structure of CIF,. Show the location of atoms and any lone pairs of electrons. In CIF, the two lone pairs of electrons can be placed one axial and one equatorial, both equatorial, or both axial. Determine the total number of each type of 90° repulsive interac- tion for each placement. F:

1. What did you notice about the shapes with and without the
lone pairs? how do the lone lairs affect the final shape?
Guidelines for Drawing Lewis Structures. STEP 1: Determine the total number of valence electrons for the molecule. STEP 2: Determine the skeletal structure arrangement of atoms) of the compound. For simple compounds the singular atom will be in the center with the others arranged around it. STEP 3: Attach each bonded atom to the central atom with...
2. Knowing that the groups of electrons around the central
atom affect the molecule shape, how do you think this will affect
the interactions between two molecules called intermolecular
interactions?
