Unformatted text preview: u will determine the product of each reaction using IR, melting point and physical observation. Using the product structures, you will propose a mechanism for each reaction. O H2SO4 O + Reaction 1: H O H O O H O O H2SO4 + Reaction 2: O H O O Procedure: Safety: Caution: Sulfuric acid is a strong acid and will burn your skin and eyes. You must wear gloves and eye protection while using sulfuric acid (and during the rest of the laboratory as well). Immediately clean up all small spills with 5% sodium bicarbonate. Upon contact with skin, immediately flush with water for at least 20 minutes. Then seek professional attention. Synthesis Weigh approximately 1.50 g of 1,4-dimethoxybenzene into a 50-mL Erlenmeyer flask containing a 1” stir bar and record the exact mass of the sample in your laboratory notebook. Add 5 mL of acetic acid followed by 3.5 mL of either 2-methyl-2-butanol or DL-3-methyl-2-butanol. Cover the Erlenmeyer flask with a watch glass when possible to minimize the odor in the lab. Place the Erlen...
