Preparation of Benzoic Acid Place about 4 g of dry ice in a dry beaker with about 5 mL anhydrous ether. Moisture from the air will condense on the surface of the dry ice; this will interfere with the reaction, so weigh out the dry ice as quickly as possible and begin the reaction immediately. Using a Pasteur pipet, transfer the Grignard reagent solution onto the dry ice. When all the Grignard
