Read each question carefully and answer to the best of your ability. Use your knowledge of VSEPR theory to determine molecular geometries and bond angles.
1. According to VSEPR theory, what is the electron geometry around the central atom in a molecule with four electron domains and no lone pairs?
Trigonal planar
Tetrahedral
Bent
Trigonal pyramidal
2. Which of the following molecules has a trigonal planar molecular geometry?
CH₄
NH₃
BF₃
H₂O
3. The VSEPR theory states that electron domains around a central atom will arrange themselves to minimize .
4. A molecule with two bonding domains and two lone pairs will have a molecular geometry.
5. Lone pairs of electrons exert more repulsion than bonding pairs.
True
False
6. The ideal bond angle for a trigonal planar molecule is 120 degrees.
True
False
7. Describe the molecular geometry and approximate bond angles for the water molecule (H₂O). Explain how lone pairs influence its shape.
8. Compare and contrast the molecular geometries of methane (CH₄) and ammonia (NH₃), explaining the role of lone pairs in any differences.
Refer to the diagram below showing various VSEPR geometries to answer the following questions.
9. Identify the electron domain geometry and molecular geometry for a molecule represented by AX₂E₂.
