Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....

Q: Calculate the expected mass of both methyl salicylate and
aspirin assuming 100% yield.
EXPERIMENT7 PREPARATION OF PHARMACEUTICALS Fischer Esterification Reactions Almost 2500 years ago, physicians such as Hippocrates recommended that patients chew on the bark of the willow to alleviate pain. The active ingredient in willow bark was found to be salicin, a compound made of a molecule of salicyl alcohol bonded to a p-D-glucose molecule. In the stomach, the bond between...

Make a diagram of each case using root cause analysis Case #1: Gas tap without burner Two-way gas taps are commonly installed in school science laboratories. For one reason or another, not all gas taps are connected to Bunsen burners. In an attempt to light a Bunsen burner, a student mistakenly turned on the adjacent gas tap not connected to the burner. Gas emitted from the gas tap burst into flames. Fortunately, the student was able to turn off the...

What is the theoretical yield (in grams) and percent yield of your
triphenylmethanol product in this experiment? (Weight of
triphenylmethanol: 0.060g)
BACKGROUND AND THEORY The Grignard reaction was one of the first organometallic reactions discovered and is still one of the most useful synthetically. By reacting an organohalide (usually a bromide) with magnesium in ethereal solvent, carbon becomes a nucleophile. Grignard reagents are the starting points for the syntheses of many alkanes, primary, secondary, and tertiary alcohols, alkenes, and carboxylic...

Experiment 8 Name: Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of cach reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms...

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
