Read each question carefully and answer to the best of your ability. Refer to your knowledge of VSEPR theory and molecular shapes.
1. Which of the following molecular shapes has bond angles of approximately 109.5°?
Linear
Trigonal Planar
Tetrahedral
Bent
2. According to VSEPR theory, what causes the repulsion between electron pairs?
Proton-proton repulsion
Electron-electron repulsion
Neutron-neutron repulsion
Bonding attractions
3. The VSEPR theory stands for Valence Shell Electron Pair Theory.
4. A molecule with three bonding pairs and one lone pair around the central atom will have a molecular geometry.
5. The molecular geometry of carbon dioxide (CO2) is .
6. Lone pairs of electrons exert more repulsion than bonding pairs.
True
False
7. The molecular geometry of water (H2O) is linear.
True
False
8. Explain how the number of lone pairs on a central atom affects the molecular geometry.
9. Draw the Lewis structure for Ammonia (NH3) and predict its molecular geometry.
