MDC Calculating Percent Yield Before & After Recrystallization Report

Description

Instructions:

Include an introduction explaining the reaction for this experiment.
Write down the balanced chemical reaction for the experiment.
Draw the mechanism for the reaction carried out in the experiment.
Summarize the video below. Write them as procedures or instructions for someone to carry out in a lab setting.
For example:
1- Protect the hands and arms by wearing gloves
2- Weigh 0.3g of X compound and 0.5g of Z compound. Transfer the reagents
3- Add ……. Etc
4-…..etc
THE VIDEO THAT YOU MUST SUMMARIZE IS THIS ONE : https://youtu.be/_sO6at1VcCs
Calculate limiting reagent, percent yield and percent recovery after recrystallization based on the data below:

Compounds Amounts

anthracene 0.520 g

maleic anhydride 0.320 g

crude Diels Alder product 0.623 g

recrystallized Diels Alder product 0.550 g

Experimental melting point of recrystallized product 266 – 268 Celsius

Xylenes (solvent) 35 mL

Discuss errors such as low or high yields, melting points, etc.
Cite references used to help you write this lab report.
Answer post lab questions 1-4 from handout on page 163

Post-Laboratory Questions

1. Calculate the percent yield for your product, before and after recrystallization.

2. Calculate the percent recovery from the recrystallization.

3. The product of this reaction can be hydrolyzed by water. Show the product of hydrolysis.

4. Recrystallizing an anhydride (such as the product of this reaction) from water or from an alcohol is rarely a good idea. Explain why.

5. (a) Compare the carbonyl region of your IR spectrum with that of maleic anhydride. What are the similarities? What are the differences? (b) Does your IR spectrum allow you to confirm that the structure of the product is a combination of the two reactants? Briefly explain.
