GEOMETRY
For each of the following molecules, draw the Lewis Diagram and tally up the electron pairs (bonding and lone).
Remember, double and triple bonds count as ONE bonding pair! Then, identify the correct the molecular shape and make
a sketch of the shape. Indicate the bond angle. Show dipole moments to determine if the molecule is polar or nonpolar
overall.
