On the following pages are two problems. You have a molecular formula, an IR, a 1H NMR and a 13C NMR. For each problem: a. (1 pt) Calculate the index of hydrogen deficiency. b. (4 pts) Propose a structure that is consistent with the spectra. c. (1 pt) Indicate the important peaks in the IR and what features in your structure they correlate to. (Ignore the fingerprint region.) Keep in mind that the IR can sometimes be confusing. d. (2...
