1- Use a wave model of bonding to explain why the He2 molecule doesn%u2019t exist.
2- Draw the orbital energy diagram for O2. What feature of oxygen%u2019s properties is revealed in this diagram?
3-For the following molecules or ions, draw the Lewis dot pictures and also draw a figure indicating the structure. In particular please be clear about the location of lone pairs in your structural drawing.
a) CO32
b) SF4
c) SO2
d) NH4+
e) PO43-
4 - Are SF4 and SO2 polar or nonpolar and why?
5-Briefly explain London dispersion forces
6-Why is the boiling point of octane, C8H18, higher than that of methane, CH4, if they are both nonpolar molecules?
7-Using a diagram to illustrate your answer, explain the effect of temperature on the vapor pressure of a liquid.
8-Using a diagram to illustrate your answer, explain the differences in vapor pressure of two molecules, A and B, if the intermolecular forces of B are greater than those of A.
