and react it with benzoin to form the 3o alcohol 1‚2-diphenyl-1‚2-propanediol‚ through an addition reaction pathway. Introduction: Grignard reagents are alkyl or aryl-magnesium halides that act as the nucleophile in Grignard reactions‚ where ketones are reacted with the reagent‚ then treated with acid to produce an alcohol. In the case of this experiment‚ methylmagnesium iodide was created from methyl iodide and magnesium metal. It acted as the Grignard Reagent in Part B upon which it was reacted

First‚ the refreshing‚ minty‚ invigorating‚ natural flavor of Wintergreen pleases the taste buds to give a tasty‚ tobacco‚ nicotine treat. This is a plus; however this is not the best element of the Grizzly Long Cut Wintergreen taste. Grizzly is known in the “dipping world” to give the average nicotine lover‚ a kick in the butt. The buzz received off of a Grizzly product‚ in this case Long Cut Wintergreen‚ lasts a lot longer than other smokeless tobacco products. Discussion forums

The Effect of the Concentration of Sulphuric Acid on the Reaction Rate with Magnesium Sarah Cain SCH 4UB Mr. Lankin April 1‚ 2009 Introduction The nature of the problem is to design an investigation that examines a variable affecting the reaction rate. In this experiment‚ magnesium will be reacted with different concentrations of sulphuric acid. The reaction is shown by the following chemical equation: H2SO4 (l) + Mg (s) → MgSO4 (aq) + H2

The purpose of the experiment was to perform an electrophilic addition reaction by the bromination of cinnamic acid. The product of this reaction is 3-Phenyl-2‚3-dibromo propionic acid‚ which is purified by recrystallization. Cinnamic acid (3-phenylprop-2-enoic acid) is an unsaturated carboxylic acid. The electron rich π cloud (see Figure 1) in the double bond of this structure is nucleophilic and can be considered a Lewis base. It can therefore be saturated by the addition of a halogen to the double

Acid Base Titration bre’ana March 1‚ 2013 Purpose: The purpose of this experiment is to determine the concentration of a solution of NaOH by titration with a standard solution of HCl. It was also the purpose to determine the concentration of a sample of white vinegar by titration with a standard solution of NaOH. Introduction: Using the method of titration is how the experiment gets to the conclusion of the concentration of a solution. When doing this experiment‚ measurement is very important

Naomi Lee Japitana CFP-E BSA February 4‚ 2014 NSTP Reaction Paper about the movie “Frozen” “Frozen” was one of my favorite movies so far in my teenage life. It remains to be different from other movies that I had watched. Yes‚ most Disney movies are almost all about love‚ love and love for opposite genders but this movie is really not. I mean‚ it is about love but a kind of love that everyone else can ever be satisfied. This is about the love of a family specifically‚ the love a sister to another

Introduction We are going to do an experiment to see how surface area effects the rate of reaction when added to hydrochloric acid. I will add calcium carbonate (marble chips) to hydrochloric acid. When calcium carbonate is added to hydrochloric acid a reaction takes place. The solution fizzes and gives off the gas carbon dioxide. I will collect this gas in a gas syringe and will time how long it takes for the reaction to produce 100cm3 of carbon dioxide. CaCO3 +2HCL Co2 +CaCl2 +H2O CalciumHydrochloricCarbonCalciumWater

Starting with the weight of .198 g of salicylic acid‚ the moles of the reactant was determined to be 1.43 x 10-3‚ as shown in Equation 3. The purified aspirin product was a white powder that had a weight of .140 g. The number of moles of the purified aspirin product after extraction was 7.77 x 10-4 as shown in Equation 4. These two moles calculated a chemical yield of 54.3% as shown in Equation 5. The melting point of the pure aspirin product was ranged at 117.8-125.2C as shown in Table 1.
