Emmanuel Omolola Orgo Chem 2 Sec #1 (4-6pm) October 8, 2012 Grignard Reaction with a Ket one: Triphenylmethanol bottom: The purpose of this exeperiment was to synthesize tripheymethol from a Grignard reagent, phenylmagnesium, bromide, bromobenzene, and benzophenone. Since the Grignard reagent is such a buckram nucleophile and base, it is important to prevent urine and other protic real(a)s from interfering with Grignard reagent ar developed. The experiment involved ii reactions. First the Grignard reagent, phenylmagnesiumbromide, was synthesised from bromobenzene, magnesium and diethyl diethyl quintessence. at one time produced, the Grignard reagent was indeed employ to synthesise triphenylmethanol by reacting it with benzophenone. Reaction final work: Theory Reaction Mechanism The halide can be Iodide, chloride, or bromide, but fluoride is to a fault unreactive level Magnesium to be apply. usually anhydrous diethyl ether is the dissolving agent used when preparing Grignard reagents, and its produces an exothermic reaction. Grignard reagents atomic number 18 potently basic, and react straightway with proton donors. Carbonyl containing compounds to produce alcohols is one of the chief(prenominal) reactions in the reagents.

This explains the nose candyyl pigeonholing is more polar and the ascorbic acid is more electrophilic. Producers: In this experiment, we used bromobenzene, and magnesium to produce our cloth triphenylmethanol. We used .112 moles of bromobenzene, and .0103mole of magnesium moles of methyl benzoate was the limiting reagent in the experiment. In calculating the theoretical yields. We used the limiting reagent multiplied by the molecular weight of the product. The world of the Grignard reaction began after around ten minutes of blueish heating was applied to thereaction flaskful containing the crushed magnesium turnings and first gear portion of the bromobenzene/anhydrous diethyl ether solution. This initiation was evident by cloudiness and graying of solution as well as...If you want to shorten a full essay, decorate it on our website: Ordercustompaper.com
