Can you explain how the J values on HNMR support an E or Z configuration as it relates to the reaction of 2,3-dibromo-3-phenylpropanoic acid with acetone as the solvent, then with water as the solvent, to yield Beta-Bromostyrene. J values for Acetone give a ratio of 1:2 98%-cis 2%-trans. For Water it's 1:4 20%-cis, 80%-trans. Thank you.

Based on the Wittig Reaction exp. below, please answer a) and
b). In b) you can disregard the part about the IR, just please
interpret and assign protons, shift values, which protons are for
which groups, etc on the HNMR. The % yield was 34%, and MP was
lower than expected (to assist with answering part a). This should
be all the information you need to answer the question.

Experimental Data Only report the IR absorptions that provide diagnosis for the major functional groups. Copies of your spectra will be included in your lab report with this information written on the spectra. However, the information should also be included in the body of the report in a text format similar to the example given below IR cm1: 1735 (C-o); MS:...

Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...

Can you please explain in simple terms the methods of this experiment? I'm having difficulty visualizing and understanding what is being done. I have copied and pasted some of the text from the article. Thank you! Abstract : Obesity, high-fat diets, and subsequent type 2 diabetes (T2DM) are associated with cognitive impairment. Moreover, T2DM increases the risk of Alzheimer's disease (AD) and leads to abnormal elevation of brain beta-amyloid levels, one of the hallmarks of AD. The psychoactive alkaloid caffeine...
