nside a 125-mL Erlenmeyer flask, add 6.1 mL of methyl benzoate, and 12mL of sulfuric acid. Place this flask into an ice bath. In a separate flask, add 4mL of sulfuric acid and 4mL of nitric acid; place this flask into an ice bath. Using a pipette, transfer the mixture of flask #2, into the original flask, (#1). Allow the reaction mixture to warm up to room temperature and wait 15 minutes. After, pour the mixture into a 100mL beaker, filled with 50g of ice. Prepare a vacuum filiation. Pour the reaction, then first wash with cold water, and then wash with 10mL of cold methanol twice. weight the product and Save it to be analyzed by melting point . The remaining of the product is recrystallized. With a hot methanol  determine the melting point and NMR what is the theoretical yield?
