Base the answers off of the NMR and IR spectra provided. I submitted an example of someone else’s work as well, but this NOT THE SAME AS MY DATA. Please follow format and make sure my spectra is annotated correctly. My sample is not pure, so please describe the other peaks. We did the reaction starting cinnamaldehyde FYI. NMR Analysis. Discuss the obtained 1H-NMR data for your product – based on your NMR data, how pure is your compound? Discuss all peaks in the spectrum – splitting patterns, chemical shift values, integration values, and a brief justification for the assignment of each signal (functional groups, EWG vs. EDG, etc). You can combine parts of your discussion for Hs in similar environments (like for aromatic protons), especially if they overlap in your spectrum. If you see peaks for impurities (other compounds than 9-fluorenone), discuss them briefly. Connect your TLC data to your NMR spectra – did your TLC plates indicate a pure or impure substance? How does that compare to your NMR data in regard to purity? Please refer to your NMR checksheet on your postlab assignment for help with annotation and discussion of peaks. Think in the style of claim, evidence, reasoning to help with you discussion! Use the example NMR paragraph provided on Canvas as a guide! IR Analysis
How does the IR prove the cinnamyl alcohol was successfully synthesized? Discuss your IR data – be sure to include all peaks (noted in your table from the post lab) and what functional group they belong to. Does the IR prove full conversion of the starting material to the product? Is there any clear evidence in the IR of leftover starting material? Does your IR data match what you observed in your NMR data and on your TLC plates? Any impurities you observed on your NMR should also be labelled and discussed in the IR data noting obvious key peaks only (except acetone – that came from cleaning your NMR tube). Think in the style of claim, evidence, reasoning to help with you discussion! Conclusions
Start this paragraph with “In conclusion, the reduction of cinnamaldehyde to cinnamyl alcohol was successful/unsuccessful…” “Success” should be related to whether you were able to make your target product as evidenced by the NMR/IR data. Now that you have the full story and spectroscopic evidence, tie all pieces of data together (TLC plate observations, NMR/IR data, yield, appearance) in a few sentences. Thinking back to your Postlab answers and your NMR/IR data, what is the take-home message of this experiment? Were there any major sources of error? What are TWO 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 by TLC, work-up, and purification could be improved.

This is a PRE lab report. the procedure for it Is already done for you. you just need to copy AND paste the protocol onto the lab report template. I Will attach both. lab has not happened yet. you need to research this topic beforehand and write about it in the introduction followed by the objective of the lab. if you use sources make sure to use superscript format for it. superscript goes after the period. include It in references. intro should be at least a page long. it should be detailed.
you need to also do the lab equipment portion as well as the reaction and chemicals. do not morph the formatting of the template.
if you have questions let me know please. we are required to bring a polyester water bottle to class to experiment on. so you can talk about that too in the intro. these lab reports are hard to do because we have to usually do our own protocol and research. but I have it given to you. so good luck
just to clarify what needs to be done:
intro with objective
reaction
equipment
Chemical
Procedure (copy and paste from what I have attached for u in a separate doc. you can remove the procedure from the template since that is just an example)

This week you will be discussing electrochemistry. It is important to understand how redox (reduction/oxidation) occurs in the human body, and how your diet and lifestyle contributes to these mechanisms. This is especially true considering how essential the balance between free radicals and antioxidants is for proper physiological function. We often hear about the importance of antioxidants in foods and vitamins, but have you ever considered how impactful they may be for your body specifically?
Initial Response:
What contributes to free radicals in the body? How are they introduced?
What types of consequences can occur if there is an excess of free radicals in the body?
Do you take radicals in the body into consideration when planning your meals?
What types of changes does this research encourage you to personally make?

Permeable: Literature reviews represent authoritative and up-to-date reports on a specific scientific topic in the science community. They are constructed through the summarising and critical analysis of previously published articles without introducing new data. The text will be referenced in a style that is particular to the journal where they are published.
Important information: You should include a short introduction, concise critical analysis of the literature and a short concluding statement. You may use up to 15 papers as references. They are all to be chosen by you.
Main Task: Write a literature review based on “Techno-economic analysis of a nature-inspired biorefinery producing biomass-derived activated carbon for energy storage applications.”
Instruction: The content should be referenced appropriately. Here please use the referencing style of the journal ‘CHEMICAL REVIEWS’ (ACS) – https://pubs.acs.org/journal/chreay.
