Recommended Problems
I believe there are very few problems to be done that you would not derive some benefit from. What I have done in the following list are to pick problems that I feel depict particularly significant concepts, or are very similar to the way in which I ask questions.  This list, however, represents the minimum problems you should do.  Remember that one of the things I told you the first day of class is that one of the ways to do well in chemistry is to work lots of problems.
