Introduction This lab was performed to prepare a Grignard(phenylmagnesium bromide) reagent. In this lab, phenylbromide was added to magnesium and reacted with anhydrous diethyl ether to form phenylmagnesium bromide. Techniques of inducing a reaction via heat and stirring were employed. A Grignard reaction proceeds by reacting a carbohydrate group attached to a halogen with Magnesium. The resulting product is very reactive and basic and can be used for many other further reactions. Experimental Procedure 1.5 g of Magnesium turnings were placed in a round-bottom flask and covered with bromobenzene. The round-bottom flask was assembled with another piece of glassware. This apparatus was clamped and heated in a sand bath. 4.0 mL of anhydrous diethyl ether mixed with ~1 mL of bromobenzene was then added to the flask. When the reaction did not occur from heat alone, the magnesium was continuously tapped with a metal spatula to induce a reaction. Once the reaction began, the apparatus was replaced
