Dry lab report on (Preparation of Ethyl 4-aminobenzoate)
Description
You should be able to work out a percentage yield for your virtual experiment using the data. You can then compare yield, MP/BP and IR to the expected results in literature.
Information form the Rubric. Percentage of grade in Brackets.
Introduction (20%)
Should include the following
Aim of the report
Background on the molecule you have chosen to synthesize
Mechanism for the synthesis reaction – a diagram and your understanding of it.
Important theory behind the experiment
Method (25%)
Should include the following
Method should cover both the synthesis of the molecule and purification of it from any impurities.
Comparison of method or part of method to at least one alternative
Demonstrate understanding of why each step is being carried out
Considerations of Health and safety issues (major points should be clear in the method but an appendix at the end of the report for all chemicals used in the experiment, this includes products and impurities).
Detail of the method you have chosen so that someone else could replicate the method
Results (20%)
Your report should include the following:
Percentage yield calculations using your set of dry data, see separate data sheet for your data set.
Analysis of IR results for your compound including identification of key peaks and possible impurities. This can be for the product and starting compounds.
Analysis of melting point/boiling point data
Discussion and Conclusion (30%)
Should include the following:
Compare results with what you expected to get
Analyse the experimental error cause and size of errors and their impact.
How they could be avoided?
What do the results mean? – link them back to the theory
How do they compare with others work? This should be referenced sources not other data in the results for students.
Link your results back to your objective in your introduction.
Discuss the strengths and limitations of your experiment
Use of referencing (5%)
Appendix
You may like to include the following as an appendix, note all key information should be in the main part of the report with appendices used for supporting information.
H&S information equipment lists detail of any calculations carried out (key details should be in the body of the text but if you want to break down the steps in more detail you can add this as an appendix).
