4. SEP Develop Models Based on the completed example for water in Figure 1 and the data in
Figure 2, annotate the diagrams for H2S and SO2 shown in Figure 1. Include (a) the
electronegativity values, (b) the partial charge symbol for each atom in a bond, (c) the dipole
vector for each bond, (d) the electronegativity difference between each bonded pair of atoms, (e)
the resulting overall dipole vector for each molecule.
5. SEP Analyze Data Compare the completed diagram for H2O and the diagrams you drew for H2S
and SO2 in Figure 1. Which of these three molecules is the most polar? Which is the least?
Explain your reasoning.
6. SEP Develop Models Based on the data in Figure 1 and Figure 2, annotate the diagrams for
NH3, NF3, and PH3 in Figure 1. Include (a) the electronegativity values, (b) the partial charge
symbol for each atom in a bond, (c) the dipole vector for each bond, (d) the electronegativity
difference between each bonded pair of atoms, (e) the resulting overall dipole vector for each
molecule.
