Molecular Geometry Practice Problems
Basic Overview
1. According to VSEPR theory, how will the lone pairs and bonded atoms try to arrange themselves (close
together, far apart, in a line, etc.)?
2. In a geometry drawing, how do you show bonds coming toward you, away from you, and to the sides?
3. Do a geometry drawing for QX4, which has one X going away, one coming toward, and two on the side.
4. Name the molecular shape of each type of compound listed below (use your notes):
a. AB
b. AB2
c. AB3
d. AB4
e. ABE
f. AB2E
c. AB3E
d. AB2E2
