Your answer is incorrect. The volatile organic compounds (VOCs) produced by decomposing tissue and organs were studied in an effort to identify possible human-specific markers (PLOS ONE 2015 10(9): e0137341.). Of 452 VOCs isolated, six were found to be unique to humans, so this may prove to be a useful tool for forensic chemists trying to determine the source of unidentified remains. There are two doublets in the expected ¹H NMR spectrum of the following human-specific VOC. Identify the protons giving rise to each doublet.

Tom, an analytical chemist, bought a bag of decaffeinated coffee from a grocery store. However,Tom suspected that he might have received regular coffee and therefore decided to analyze hiscoffee for caffeine. In the lab, he took 0.5 mL of the brewed coffee and diluted it in water tomake a 100.0 mL solution. He performed four analyses and found the concentrations to be 4.69,3.99, 4.12, and 4.50 mg/L, respectively. (Assume the density of all solutions is 1.000 g/mL,1oz= 28.35 mL).(a) Report the concentration (in mg/L) of caffeine in the brewed coffee using the format asaverage ± standard deviation. (Note this is not the concentration in the diluted solution.)(b) Look up the caffeine content of regular vs. decaffeinated coffee. Do you think that Tom wasgiven the wrong type of coffee?(c) Caffeine intake of 300 mg per day reportedly has no adverse effects in the vast majority ofthe adult population. If Tom drinks 3 cups (8 oz/cup) of this coffee daily, is his intake withinthis known safe…
