In one example of this reaction the reaction of an alkyl chloride with potassium iodide is generally carry out in acetone to maximize the amount of alkyl iodine that this formed. Why does the solvent increase the amount of alkyl iodide. Hint: potassium idioide is soluble in acetone but potassium chloride is not.

- One of the classic electrophilic aromatic substitution reactions is nitration. The addition of a nitro group to the ring is generally conducted with nitric acid and it is subject to the directing effects of the substituents on the ring in the starting material. In this experiment we will investigate the nitration of phenylacetic acid as shown below.There are several things to consider with this reaction that can be addressed through analysis of the products made under various reaction conditions. What follows is a list of questions that we want to answer in a logical, data supported way. Spectra and other data will be provided along with guidance as to how to answer these questions. This report is expected to be lighter on the procedure portion, and considerably longer on the discussion portion than normal What kind of group is present in the starting material?
