3. Indicate the interesting peaks you would expect to find in the IR spectra for each molecule. Then, predict the number of signals you would expect to see in the 13C and 1H NMR spectra. Indicate the chemical shift of any interesting peaks in the 1H NMR. The first one has been completed as an example. $$^{13}C$$ NMR (# lines) $$^{1}H$$ NMR (# peaks) Functional group(s) Interesting peaks in IR ($$cm^{-1}$$) Interesting peaks in $$^{1}H$$ NMR (> 4 ppm) 7 5 Aromatic ring 3050 (=C-H) 1500, 1600 (C=C) ~7.0 (aromatic H) NA, below 1400 $$CH_3$$ = $$CH(CH_3)_2$$ = NA Broad peak between 2-5 ppm (OH) $$^{13}C$$ NMR (# lines) $$^{1}H$$ NMR (# peaks) Functional group(s) Interesting peaks in IR ($$cm^{-1}$$) Interesting peak in the $$^{1}H$$ NMR (ppm) $$^{13}C$$ NMR (# lines) $$^{1}H$$ NMR (# peaks) Functional group(s) Interesting peaks in IR ($$cm^{-1}$$) Interesting peak in the $$^{1}H$$ NMR (ppm)

Suppose that Edison and Hilary are the only suppliers of shoes in a particular market. The following table shows their annual supply schedules. Edison's Quantity Supplied Hilary's Quantity Supplied Price (Dollars per pair) (Pairs per year) (Pairs per year) 10 0 16 20 16 28 30 24 36 40 28 40 50 32 44 On the following graph, plot Edison's supply of shoes using the green points (triangle symbol). Next, plot Hilary's supply of shoes using the purple points (diamond symbol). Finally, plot the market supply of shoes using the orange points (square symbol).
