Abstract: The purpose of this lab was to synthesize triphenylmethanol from benzophenone and bromobenzene by the formation of a Grignard compound with the reagents bromobenzene and magnesium metal. The bromobenzene was first transformed into the Grignard compound and was then reacted with the benzophenone to make the final product. The mixture was then mixed with sulfuric acid and the organic layer was extracted via a separatory funnel. The mixture was then recrystallized from methanol and was allowed

Dissolve a single tablet in 500 mL of distilled water in a conical flask and add about 150 mL of distilled water‚ 5 mL of 0.6 mol L−1 potassium iodide‚ 5 mL of 1 molL−1 hydrochloric acid and 1 mL of starch indicator Solution. 33. Use the buret to deliver a stream of titrant to within a couple of mL of your expected endpoint. 34. Use a wash bottle to rinse the sides of the flask and the tip of the buret‚ to be sure all titrant

Introduction: Density is defined by its mass per unit volume‚ and is most often written in mathematical terms as; d = m / v Mass is usually given in grams‚ g‚ and volume is given in cubic centimeters‚ g/cm3‚ or‚ grams per milliliter‚ g/mL. Density is not a property that depends upon the amount of substance present. For example‚ one gram of lead and one ton of lead have the same density. Density also does depend on temperature. For instance cold water is denser than warm water;

Repeat for the other 4 Acid - Base Indicators Part 2 Step 1: Obtain acid‚ in a 100 ml Erlenmeyer flask add 35 ml of an Unknown HCl solution. Step 2: Add an indicator to the acid‚ select the flask and add 2 drops of phenolphthalein indicator. The indicator menu is available under the chemicals main menu (ChemicalsIndicators) or the context menu. Step 3: Fill buret with NaOH‚ obtain a 50

Goal(s): To study the effect of concentration on the rate of a reaction‚ and to find the order of the reaction in each reactant and write a rate equation. Background Theory: Chemical reactions occur at different rates that ultimately depend on their concentration‚ the temperature‚ the usage of catalysts‚ the nature of reactants‚ like the surface area of the particles. Concentration‚ for instance‚ increases the number of molecules or particles in a certain volume‚ so collisions will become more

Identification of a Conjugated Diene from Eucalyptus Oil Introduction: When two carbon-carbon double bonds are positioned next to one another‚ a conjugated diene is formed. Conjugated dienes undergo a cycloaddition reaction with certain double bonds to afford cyclohexenes and related compounds. The reaction is named Diels-Alder. The Diels-Alder reaction is between 1‚3-butadiene and ethylene to produce cyclohexene + dienedienophile. The mechanism of the Diels-Alder reaction is classified as a

Aliphatic hydrocarbons are divided into three classes: alkanes (e.g. methane‚ ethane and propane) have only single bonds‚ and are said to be saturated; alkenes (e.g. ethene and propene)

Procedure/Observations: 1. Weigh out ~280 mg of acetanilide in a 10 mL r.b. flask with a stir bar. 2. Then‚ add 2.0 mL of glacial acetic acid using a calibrated Pasteur pipet. 3. Stir the mixture until all of the acetanilide has dissolved. It may be necessary to add more acetic acid dropwise until full dissolution has occured. 4. In the fume hood‚ add 0.6 mL of 4.1 M bromine solution in acetic acid. 5. Cap the round bottom flask before returning to the bench. 6. For 15-20 minutes‚ stir the reaction
