Sketch the simple Lewis dot structures and the predicted VSEPR
shapes for each of the following species. Be sure to clearly indicate
lone pair electrons, multiple bonds (double or triple), and any three-
dimensionality (using dashes and wedges). For any ions, don’t forget
to account for the charge when calculating valence electrons! Only
expand the octet of the central atom when absolutely necessary.
A. CO2
B. CS2
C. SeCL
D. SO2
E. SO32-
F. CO32-
G. N3-
