A student in an organic chemistry lab prepared dibenzalacetone according to the following chemical reaction using excess base. It is important that the molar ratio of the readouts in this reaction be 2:1. a) If the student started with 10.6 g of benzaldehyde and 2.9 g of acetone, what is the theoretical yield of the product? b) If 10.5 g of the yellow product is obtained, calculate the percent yield. c) What would be the expected product for a 1:1 mole ratio of the reactants? d) Another student carries out this reaction using 16 moles of benzaldehyde and 10 moles of acetone and obtains 6 moles of dibenzalacetone. i) What is the limiting reactant? ii) What is the excess reactant and how many moles of this reactant will be left al the end of the reaction? iii) What is the percent yield of this reaction? iv) What is the actual grams of the yellow product obtained in this reaction?
