formal lab report, both available via Canvas Files.
FORMAL LAB REPORT, General
A formal lab report is required in conjunction with some of the experiments in each
chemistry course. It is your chance to demonstrate to your professor or TA how well you
understand the experiment and the chemical principles involved. A formal report is different
than a term paper. It should be written in a scientific style, which is not the same style used
for English or philosophy papers.
The keys to effective technical writing are organization, brevity, clarity, and an appreciation
of the needs of the reader. You must write clearly and be thorough, but concise. Do not
ramble. The best way to avoid rambling is to first prepare an outline of the report and stick
to it. Always use complete sentences. Bulleted lists are okay in a lab notebook but are
unacceptable in a formal report. Formal reports must be typed. Use 1.5 line spacing, 1-inch
margins, 12 pt font and 8.5×11 inch paper. Only use third person, past tense. Also, proofread
well.
While report sheets may be a joint effort, formal reports must be individually written.
FORMAL LAB REPORT PRACTICE – Conclusion
The purpose of the Conclusion section is to summarize the pertinent concepts discussed in
the Result & Discussion section. Always begin your Conclusion by clearly stating your
results and the “goodness” or significance of your results, and relating them to ideas
presented in the introduction. In other words, if the objective of the study was to determine
the percent calcium carbonate in an unknown sample, you should restate the percentage, with
its uncertainty, in this Conclusion section.
Important observations may go in this section as well. Discuss the significance of the results.
When possible, compare your results with literature values. Discuss significant errors and
suggest improvements to the procedure or possible ideas for additional experiments that
could further support your conclusion.
Then make a concluding statement(s) and relate your conclusion to the ideas presented in the
introduction. Note: Stating that “overall the experiment went well” or that “I learned how to
use a piece of equipment” are not strong conclusions.
The conclusion is not to be a lengthy discourse. One paragraph (about four to seven
sentences) is the amount to be presented in conclusion.
Assignment: Practice writing a “Conclusion” section on the lab specified in
the syllabus and submit on the date indicated on the syllabus. Should be typed
in word document and submit electronically!

Hello, I have to give a presentation on the study “IL-18 Immunotherapy for Neovascular AMD: Tolerability
and Efficacy in Nonhuman Primates”, the research document is attached below. I would like you to write what I can say for my presentation under the headings “Introduction”, “Objectives” and “Methodology”.
I am to present for maximum 3 minutes on those 3 headings.

I have attached an example and instructions as well as my data. 1. NMR Analysis
Did you successfully synthesize the target compound? Did you successfully purify the product via recrystallization? Discuss your NMR data to prove formation of the product and to indicate success of the purification via recrystallization. Be sure to include chemical shifts, integration values, and splitting patterns along with justifications for aromatic proton chemicals (EDG/EWG). Review the video posted on Canvas for help with annotating the NMR spectrum, but remember that it uses a 300 MHz spectrum instead of a 60/80 MHz spectrum! Does the experimental data match the NMR predictions? If not, how do the chemical shifts, splitting patterns, etc. deviate from your predictions? How does the NMR prove conversion of the starting material to the product? Is there any evidence in the NMR of leftover starting material that proves recrystallization success/failure Please refer to the NMR checksheet on your postlab assignment to compare the starting material to the product. Also discuss any other impurities present (starting material, reagents, solvents, etc). Why are they there?
Think/write in the style of claim, evidence, reasoning to help with you discussion! Use your feedback on previous mini report for guidance!
2 IR Analysis
Did you successfully synthesize the target compound? Did you successfully purify the product via recrystallization? Discuss your IR data to prove formation of the product and to indicate success of the purification via recrystallization. Be sure to include stretching frequencies and what functional group they belong to. How does the IR prove conversion of the starting material to the product? Is there any clear evidence in the IR of leftover starting material? Please refer to your IR checksheet on your postlab assignment to compare the starting material to the product. Any impurities you observed on your NMR should also be labelled and discussed in the IR data (except acetone – that came from cleaning your NMR tube). Think in the style of claim, evidence, reasoning to help with you discussion!
3. Conclusions
Start this paragraph with “In conclusion, the synthesis of 3-chloro-4’-methoxychalcone via Claisen-Schmid Condensation and subsequent purification by recrystallization was successful/unsuccessful…..” Success can be evaluated as synthesis of product, purity, and/or yield. Use general trends seen in your NMR/IR/MP data to support this statement. Tie all pieces of data together (recrystallization purification observations, melting point, physical appearance, yield, NMR/IR data, etc.) in a few sentences. What was the take-home message of this experiment? Were there any major sources of error? What are some thoughtful and scientific improvements for this experiment? Remember, human error should NOT be proposed as a major error or area of improvement. Think about the reaction itself and how the chemistry, monitoring, work-up, and purification could be improved.

Use the NMR and IR data provided in images. I have attached some notes as well, also an example. I have also attached my melting point and % yield/ recovery data to use.
