Please Could your help me for these questions 2, 3, 6. My reagents were 1-bromobutane and acetone 39EXPERIMENT 3: GRIGNARD REACTION PROJECT9. Distill off the ether (BP 34.6 °C) and depending upon the boiling point of the alcohol, distillthat too. You have to look up the boiling point of the alcohol so you know at what temperatureto collect the product. You will save everything that boils over 40 °C up to the boiling point ofthe alcohol then switch receivers and collect the product. The product should be analyzed. Theether should be placed in the waste ether jar in the hood.10. Take the IR spectrum and refractive index of your product. You may also want to assess itspurity by injecting it into a gas chromatograph, using 205 DC-200 column with the columntemperature at 113°C. Make surthat the GC oven temperature is above the BP of youralcohol. Turn in your product in a labeled vial.3311. Write a detailed report about your experiment and determine the yield and % yield.

What would happen to the yield of the product if you used regular lab grade ether instead ofanhydrous ether to dissolve the carbonyl compound in steps 2 and 3 above? Write a chemicalequation illustrating the process. Use structural formulas or skeletal structures.2. What is the formula of the magnesium salt of the alcohol formed after the carbonyl compoundhas been added to the Grignard reagent? Use structural formulas or skeletal structures.3. In Step 7, what is the molarity of the dilute HCl solution you prepared? If you were to use theentire solution, how many moles of HCI would you have added?4. What is the purpose of adding the HCl solution in Step 7? Answer by writing an equation,using structural formulas or skeletal formulas for each of the following:a) the reaction of aqueous HCl with the magnesium salt in question 2.b) the reaction of aqueous HC1 with the unreacted magnesium turnings.5. If you added too much HCl and your Grignard product should undergo SN1 or SN2 reaction toform the halide, what are the structure and physical properties of this side product? Do youhave any evidence that this side product may be present? Explain fully.6. If the reaction had undergone elimination, what are the structure and physical properties of thisside product?

Set up a dry 250-mL RB flask over a magnetic stirrer in the hood. Fit the RB flask with aClaisen adapter, an addition funnel, a reflux condenser fitted with rubber tubing, and a Tefloncoated stir bar. Add 0.11 mol of magnesium turnings to the flask and cover it with a bit ofanhydrous diethyl ether. (We have two grades of ether in the lab: anhydrous and lab grade.YOU MUST USE ANHYDROUS diethyl ether at this step.)3. Measure out your calculated volume of 0.10 mol of your alkyl halide. Place 1 mL of this alkylhalide directly in the flask with the Mg turnings/ether mixture and dissolve the rest of the alkylhalide in 40 mL of anhydrous diethyl ether and place the liquid in the addition funnel andconnect it to the reaction flask. Turn the water on the condenser. (No floods please!)4. The reaction should begin shortly. The formation of the Grignard reagent is exothermic andcauses the ether (BP 34.6 °C) to boil vigorously. You can tell that the reaction is going becausethe ether will start to boil and bubbles will form around the active Mg turnings, and ether willstart to drip from the condenser. (If nothing happens after a few minutes, you may have tobreak some of the magnesium turnings with a glass stirring rod to expose fresh metal to thealkyl halide). Once the reaction starts you can add the alkyl halide solution dropwise over a 20-minute period, at such a rate that the reaction keeps boiling, but not too rapidly!! In somecases, if the Grignard reaction is slow to start, you may have to start the reaction in a test-tubeand then pour the boiling reaction mixture into the flask to get the magnesium turnings to startreacting. See your instructor if you are having difficulty in starting the Grignard.5. Once all of the alkyl halide has been added, stir the solution at room temperature until the etherstops boiling.Vacetone used = 2₂403 m/Yether. Vdiethyl ether =20ml6. Now dissolve the calculated volume of 0.10 mol of the carbonyl compound you selected to usein 20 mL of anhydrous ether and put the solution into the addition funnel you just used foradding the alkyl chloride. (Do not wash the addition funnel.) Carefully add the carbonylcompound solution to the Grignard reagent. This reaction is VERY exothermic. Have an icebath ready in case you have to cool the flask down when you add the carbonyl compound. Ifyou use an ice bath make sure that you are stirring the solution with the magnetic stirrer. Afterall of the carbonyl compound has been added, bring the solution up to room temperature andstir for several minutes. There may be a precipitate on the sides of the flask but don't worry.Some magnesium salts are not very soluble in ether.WednesAdminist7. Place the reaction flask in an ice bath. Prepare a dilute HCl solution by mixing 17 mL of 6.0 MHCl with 30 mL of water. Carefully and slowly add this HC1 mixture to the reaction flask.(You will need about 0.10 mol of HCl, but no more.) The purpose of the HCl is to helpdissolve the magnesium salts and unreacted magnesium turnings. (If you use too much HCl youmay cause the OH group of your product to be replaced by Cl! After all, some of you aremaking 3° alcohols and you recall from CHEM 200 that 3° alcohols form halides very rapidlywith HX via an SN1 process.)1468.37cmbending1364.380157.03cn125ml8. Pour your mixture into a separatory funnel. Separate the aqueous layer from the ether layer.Dry the ether layer with anhydrous MgSO4. This is a good stopping point.
