3. Is water the most polar molecule of the three molecules? Explain.

6. Would the XeF, molecule be a polar or nonpolar molecule? Explain.

7. Obtain a tbp model from the PhET and manipulate its orientation until it is as shown on the diagram below. From the model or image, what are the following angles? Record your values in the table.

8. Include a screenshot of your molecule (above) from PhET in the same orientation:

1. Hund's rules: (1) Obtain the electron configuration of a carbon atom using the Hund's rules. (2) Obtain the electron configuration of an oxygen atom using the Hund's rules. (3) Obtain and compare J of the two cases above.

6. The compounds Br2 and ICI have the same number of electrons, yet Br2 melts at -7.2 C, whereas IC melts at 27.2° C. Give an explanation as to why this is expected.

11. Does the molecule 1,3-dichloro-1,2-propadiene have a dipole moment? Draw the molecule and explain.

9. How many normal modes of vibration are in the following molecules:

7. The dipole moment of an isolated water molecule is 1.855 D. Calculate the energy in joules of the interaction between two water molecules separated by 10Awith dipoles oriented in opposite directions a) perpendicular to the distance vector between the molecules and b) parallel to the distance vector.
