Question

Match 6 compounds to their spectra using the pictures listed below. Walk through the questions for each compound to logically match the spectra. Complete the questions down below, including the ones corresponding to each compound (number of NMR signals and identity of compound as well)

UPDATE: MORE ZOOMED IN PICTURES FOR IR PEAKS DOWN BELOW

UPDATE: Here are the zoomed in pictures. Numbers start at 500 and go to 4000 on x-axis! Please also answer number of signals in NMR spectrum and identity of compound for each compound A-E along with the functional group corresponding to the circled signal in IR spectrum as well. Thank you somuch!!
