QUESTION 1 Answer all parts (a) Give an explanation of the variation in chemical shifts of the aromatic carbons in the 130C NMR spectrum of methoxybenzene. Note that the 13C chemical shift of benzene is 128 ppm Carbon Chemical Shift (ppm) CH 160 114 130 120 15 Marksl (b) Natural abundance 3C NMR spectra of organic compounds are routinely measured in the proton decoupled mode. What is the advantage of using this technique? What information about molecular structure is lost...

5. Using the GC mentioned in question 4 and the values listed on the chromatogram for the height and width (at half height) of each peak, calculate the percent composition for each product (A, B and C). Be sure to show your work. (8 points) 6. The products corresponding to each peak on the GC are the ortho, meta, and para isomers of the nitrated product shown in the scheme for reaction 1. These isomers were isolated, and a proton...

c) Using your answers to question 5 and 6a, what percent of the
mixture obtained in reaction 1 is the ortho isomer?
d) What percent of the mixture obtained in reaction 1 is the
meta isomer?
e) What percent of the mixture obtained in reaction 1 is the
para isomer?
f) Could we have used Mass Spectrometry after the GC analysis
(GC-MS) to identify which peak on the GC was which isomer? Why or
why not?
g) Could we have...

just one example/demonstration!
Data needed to be calculated is in highlighted in green boxes.
And I highlighted in red an equation (not sure if thats what you
use to calculate it) And ignore the lab instructions on completeing
a graph!! I already know how to do that in excel, just curious how
Ln (relative rate) and 1/T in K^-1 is calculated by hand*
here is the rest of that lab leading up to the question as I
know its typically...
