1. Which of the following molecules has a net dipole moment?
CO2
CH4
H2O
CCl4
2. The presence of a net dipole moment in a molecule indicates that the molecule is:
Nonpolar
Symmetrical
Ionic
Polar
3. A dipole moment arises from the unequal sharing of electrons in a bond.
4. The unit for dipole moment is the .
5. Molecular geometry plays a crucial role in determining whether a molecule has a net .
6. Explain why CO2 is a nonpolar molecule despite having polar bonds.
7. Describe the relationship between electronegativity difference and bond polarity.
8. All molecules with polar bonds have a net dipole moment.
True
False
9. Water (H2O) has a bent molecular geometry, contributing to its net dipole moment.
True
False
10. Observe the diagram of a water molecule below. The arrows represent the individual bond dipoles. Based on the diagram, explain why the water molecule is polar.
