Prelab to accompany bromination of trans-cinnamic acid(4 pts each)
The stoichiometry of the addition is 1:1, meaning that for everyone mole of transcinnamic acid, one mole of Br2 is needed to formthe addition product. The Br2 presents as a solution indichloromethane solvent. This often causes problems for studentswhen calculating stiochiometric equivalents. The bromine solutionis 10% Br2 by volume. For instance, 100 mL of solution contains 10mL of liquid Br2. The density of Br2 is 3.12 g/mL.
Calculate the number of mmol of Br2 present in 0.48 mL ofbromine solution
Calculate the number of mmol in 100. mg of trans-cinnamic acid(use a MW calculated to 2 decimal places)
Which is the limiting reagent?
What is the theoretical yield of the addition product? (use a MWcalculated to 2 decimal places)
Show all calculations.
