Read each question carefully and provide clear, concise answers. Show all your work for calculations.
1. Which of the following molecules is polar?
CO2
CH4
H2O
Cl2
2. What is the molecular geometry of a molecule with three bonding pairs and one lone pair around the central atom?
Trigonal planar
Tetrahedral
Bent
Trigonal pyramidal
3. The unequal sharing of electrons in a covalent bond creates a bond.
4. Molecules with a symmetrical geometry and nonpolar bonds are typically .
5. All molecules with polar bonds are polar overall.
True
False
6. Explain how electronegativity differences determine bond polarity.
7. Describe the conditions under which a molecule with polar bonds can be nonpolar overall. Provide an example.
For each molecule below, draw the Lewis structure, determine the VSEPR electron geometry and molecular geometry, indicate bond dipoles, and state whether the molecule is polar or nonpolar.
8. CCl4
9. NH3
