Complete Assignment M 6.2.2 Use a sheet of paper to answer the following question. When complete, take a picture of your answer and attach the file to this assignment. The reaction of (25)-2-chloro-3-methylpentane with sodium iodide yields two products: (2R)-2-iodo-3-methylpentane and racemic 3-iodo-2- methylpentane. Account for the formation of each of these two products. For each product, you should show how it is formed and what that tells you about the mechanism of that specific reaction.
