Read each question carefully and provide clear, concise answers. Show all your work for calculations.
1. Which of the following factors primarily determines the polarity of a bond?
Atomic mass
Electronegativity difference
Number of valence electrons
Ionization energy
2. A molecule with polar bonds can be nonpolar overall if its molecular geometry is:
Bent
Trigonal pyramidal
Linear or tetrahedral with identical outer atoms
All of the above
3. The unequal sharing of electrons in a covalent bond leads to a bond.
4. Molecules with a net dipole moment are considered .
5. A molecule like CO2 is nonpolar despite having polar bonds because of its geometry.
6. Explain the difference between a polar covalent bond and a nonpolar covalent bond. Provide an example for each.
7. How does molecular geometry influence the overall polarity of a molecule? Use H2O and CCl4 as examples.
8. All molecules with polar bonds are polar molecules.
True
False
9. The greater the electronegativity difference between two bonded atoms, the more polar the bond.
True
False
10. Observe the image below, which depicts a polar molecule. Identify the regions of partial positive and partial negative charge.
