The Limiting Reagent and Percent Yield

Ask Custom Question

I need helping with how to determine a limiting reagent and percent yield. For the following question, I started out with 0.60 grams of trans-cinnamic acid and added 3.5 mL of dichloromethane and 2.0 mL of 10% bromine in dichloromethane solution. I re-fluxed the reaction, and, during re-fluxing, added a couple more drops of the 10% bromine solution to get the reaction to go to product.

Please show me how to determine the limiting reagent and the theoretical yield in this case. If my solid product came out weighing 1.4 grams, the percent yield is just (actual yield/theoretical yield) x 100, right?

Solution Summary

This solution is comprised of a detailed explanation which makes this rather complicated organic chemistry question easily understandable. Additionally, this solution should help a student grasp how to approach future questions of this nature. A step-by-step guide of how to complete this problem is provided.

Solution Preview

I went through the following steps to solve the problem:
1. I calculated the molar mass of Cinnamic acid to be ~148 g/mol, using this number I see that I have 0.004 moles of Cinnamic acid.

2. 2.0 Ml of 10% by volume Br2 solution means that we have 0.2 Ml of bromine added. Using the density of bromine liquid (I found ...
