Each of the six 1H NMR spectra below corresponds to one of the 14 molecules from Questions 15-28. Determine which molecule corresponds to each spectrum, then enter the letter of the correct molecule on Canvas as your answer to the question. For example, if one of the spectra below consisted of only one singlet peak at δ 2.10, you would know that this is acetone and you would enter H as your answer.
