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.

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 pls help me identifiy the correct unknown ans explain
why this is the know for the unknown its not 2phenylethanol.
halogens is absent, differntiate is absent , nitrogen test is
absent, sulfure is absent, Br2 is absent, kmno4 absent, ignition
test absent . 2,3 dnp contains ketone ,tollens no aldehdye absent
aldehyde , iodoform test contains carbonyl in it .

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...
