Which molecule has given rise to the spectra shown below. Justify your answer with respect to IR, 1 H NMR and 13 C NMR. Keep in mind that Hs that switch with D2O usually do not show connections to other nearby H. The integrals in HNMR are marked in red text. Below the image with spectral data, you will find various shift tables for NMR IR etc.
