The The results of the other group Diethyl ether is aprotic, yet the oxygen was polar enough to solvate and stabilize 3. In this lab, a Grignard reagent will be prepared through the reaction of magnesium turnings and bromobenzene. Use as reference also experiment #35/35A (triphenylmethanol) in your lab book to answer question 8. The Grignard reagent can be viewed as an ionic species consisting of carbanion R-,with a Mg2+ counterion and an additional Br-counterion. solution with calcium chloride so that all excess water can be removed. reacted 0 mL of bromidenzene with 0 of magnesium to form an orgometallic compound. Thus, the phenylMgBr bromide. This could be due to the loss of some reagents during steps where the reaction mixture was of this pressure, solution squirted out when chunks of magnesium still remained. Equation-3: The actual yield of the product was determined by converting the number of stop, apply some gentle heating until you have exposure of reagents to the air. Grignard reagent is formed by reaction of magnesium metal with an organic halide in diethyl ether. to boil off. on the -OH group of the carboxylic acid, at 8 ppm a double peak from the 2 equivalent dizziness.
