Question

Complete the table of reactants and products for the following two reactions.

Compound	Molar Mass (g/mol)	Mass	Volume	Density (g/mL)	# Mols	Equivalents of Reactants (divide actual moles by stoichiometric moles)	Other (indicate which is limiting reactant)

Nitration of Methyl Benzoate

In a 50 mL Erlenmeyer flask, cool 6 mL of conc. H₂SO₄ in ice and add 3.0 g of methyl benzoate. Make sure the temperature stays at 0 ^oC . Using a pipet, slowly add a cooled mixture of 2 mL of conc. HNO₃ and 2 mL of conc. H₂SO₄. During the addition, swirl the flask to mix the reagents and keep it in an ice bath to ensure that the reaction mixture stays below 15 ^oC. When the addition is complete, remove the reaction mixture from the ice bath and allow it to stand at room temperature for 20 min. with occasional stirring. Pour the solution directly over about 25 g of ice in a beaker and collect the formed crystals by vacuum filtration. Wash the crystals with two 5 mL portions of ice cold water, then two 5 mL portions of ice cold methanol.

Nitration of Acetanilide

Add 2.5 mL of conc. H₂SO₄ and 1.0 g of acetanilide to a 25 mL Erlenmeyer flask. Swirl the contents of the flask until the solid dissolves. Make sure the temperature of the mixture never exceeds 25 ^oC. Cool the reaction mixture in an ice bath to 5-10 ^oC. Prepare a solution of 2 mL of conc. HNO₃ and 2 mL of conc. H₂SO₄ and cool it. Add the acid solution dropwise to the cooled acetanilide in the 25 mL Erlenmeyer flask over about 15 min. Be careful not to let the temperature of the solution exceeds 25  ^oC or product will be lost. When addition is complete, allow the reaction mixture to stand at room temperature for 20 min. with occasional stirring. Pour the mixture into a beaker containing about 50 mL of water and 15-20 g of ice. Collect the precipitate via vacuum filtration and wash it with two 5 mL portions of ice cold water.
