Read each question carefully and provide your best answer based on your knowledge of molecular geometry and VSEPR theory.
1. According to VSEPR theory, what is the molecular geometry of a molecule with two bonding pairs and two lone pairs around the central atom?
Linear
Trigonal planar
Bent
Tetrahedral
2. Which of the following molecules has a trigonal pyramidal molecular geometry?
CO2
CH4
NH3
H2O
1. The acronym VSEPR stands for .
2. A molecule with a central atom and four bonding pairs, with no lone pairs, will have a molecular geometry and bond angles of approximately .
1. Explain how lone pairs of electrons affect the bond angles in a molecule compared to bonding pairs.
2. Draw the Lewis structure for water (H2O) and predict its molecular geometry and approximate bond angle. Explain your reasoning.
1. A molecule with a linear electron domain geometry is always nonpolar.
True
False
2. All molecules with polar bonds are polar molecules.
True
False
Match the molecular geometry with its corresponding number of electron domains (bonding pairs + lone pairs) around the central atom.
1. Tetrahedral
a. 2 electron domains
2. Trigonal planar
b. 3 electron domains
3. Linear
c. 4 electron domains
