Emmanuel Omolola Orgo Chem 2 Sec #1 (4-6pm) October 8, 2012 Grignard Reaction with a Ketone: Triphenylmethanol lay: 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 nasty nucleophile and base, it is important to prevent water and other protic real(a)s from interfering with Grignard reagent ar developed. The experiment involved two reactions. First the Grignard reagent, phenylmagnesiumbromide, was synthesised from bromobenzene, magnesium and diethyl diethyl ether. at one time produced, the Grignard reagent was then use to synthesise triphenylmethanol by reacting it with benzophenone. Reaction final cause: Theory Reaction u cardinalsil The halide can be Iodide, chloride, or bromide, but fluoride is to a shifting unreactive form Magnesium to be used. Normally anhydrous di ethyl ether is the solvent used when preparing Grignard reagents, and its produces an exothermic reaction. Grignard reagents are potently basic, and react instantly with proton donors. Carbonyl containing compounds to produce alcohols is one of the chief(prenominal) reactions in the reagents.

This explains the nose candyyl group is much polar and the carbon is more electrophilic. Producers: In this experiment, we used bromobenzene, and magnesium to produce our material triphenylmethanol. We used .112 moles of bromobenzene, and .0103mole of magnesium moles of Methyl benzoate was the limiting reagent in the experiment. In figure the theoret! ical yields. We used the limiting reagent multiplied by the molecular(a) weight of the product. The facility of the Grignard reaction began after approximately ten minutes of gentle heating was applied to thereaction flaskful containing the low-spirited magnesium turnings and first portion of the bromobenzene/anhydrous diethyl ether solution. This initiation was evident by cloudiness and graying of solution as rise as...If you want to get a full essay, coif it on our website: BestEssayCheap.com
