Together with the summary of Simple Functional Group Interconversions and basic carboncarbon bond forming reactions summarized elsewhere, this summary represents all possible
reactions that could be encountered on a CHM 234 Final exam.
Generating a summary such as this is difficult, since all aspects of the reactions can't be simply
summarize, such as stereochemistry, for example. In addition, part of the issue of reactions is
recognizing how to use them outside of the context of this summary, and so please use this
summary with care and understand that there is more to doing well on the final exam than
knowing the reactions here.
