For my organic chemistry lab, we are supposed to identify all
significant peaks in each of the spectrums and label each “bond”
peak with its range in cm. I am really stuck and lost on this so
any help would be greatly appreciated.were also supposed to provide
explanations for how we know which structure is matched with each
of the spectrums.
