What type of reaction is a Grignard reaction?  What is the critical intermediate (which can be isolated and enables the final product)? Why should water be excluded from a Grignard reaction?  Since this is the case, why does just addition of a cotton ball work for our reaction setup? Why was extraction by both acid AND base necessary to arrive at highly purified benzoic acid? If we wanted to improve our set-up, we could have added a desiccant between two cotton plugs.  Why is this much better than adding drying agents such as Na2SO4directly into the solution? If we had gotten less than 50% yield for the overall process, what is at least one likely source of loss?
