Read each question carefully and provide your best answer. Show all work where applicable.
1. Which of the following molecular geometries has a bond angle of approximately 109.5°?
Trigonal planar
Linear
Tetrahedral
Bent
2. According to VSEPR theory, what determines the electron-domain geometry around a central atom?
Only bonding pairs of electrons
Only lone pairs of electrons
Both bonding and lone pairs of electrons
The size of the central atom
3. The VSEPR theory states that electron domains around a central atom will arrange themselves to minimize between them.
4. A molecule with three bonding pairs and one lone pair around the central atom will have a molecular geometry.
5. Draw the Lewis structure for H₂O and predict its molecular geometry and bond angle. Explain your reasoning.
6. Compare and contrast the molecular geometries of NH₃ and CH₄. Include a discussion of their central atoms, electron domains, and bond angles.
7. A molecule with a linear electron-domain geometry will always have a linear molecular geometry.
True
False
8. Lone pairs exert more repulsive force than bonding pairs, leading to smaller bond angles.
True
False
