Read each question carefully and answer to the best of your ability. Show all work where applicable.
1. What is the electron domain geometry of a molecule with two bonding domains and two non-bonding domains around the central atom?
Linear
Trigonal planar
Tetrahedral
Bent
2. Which of the following molecules has a trigonal pyramidal molecular geometry?
CO2
H2O
NH3
CH4
3. According to VSEPR theory, electron domains will arrange themselves to minimize between them.
4. A molecule with a central atom having five electron domains and zero lone pairs will have a electron domain geometry and molecular geometry.
5. Lone pair-lone pair repulsion is generally stronger than lone pair-bonding pair repulsion.
True
False
6. A molecule with a tetrahedral electron domain geometry will always have a tetrahedral molecular geometry.
True
False
7. For the molecule SF4, determine the electron domain geometry, molecular geometry, and approximate bond angles. Explain how lone pairs influence the bond angles.
8. Compare and contrast the molecular geometries of CH4, NH3, and H2O. Discuss the role of lone pairs in determining their shapes.
Match the electron domain geometry with its corresponding molecular geometry when lone pairs are present.
