CHAPTER 1 SOLUTIONS
1. Use arrow pushing to explain the following reactions.
When drawing arrows to illustrate movement of electrons, it is important to remember
that electrons form the bonds that join atoms. The following represent heterolytic-type
reaction mechanisms:
This is an example of an S
N
2 reaction mechanism converting an alkyl
iodide (iodomethane) to an alkyl nitrile (acetonitrile). Arrow pushing is illustrated
below:
