Question

You are provided with the molecular formula for each compound. calculate the unsaturation index for each problem. -u2C+2+N-X-H For IR, determine the functional groups present and annotate the absorbances that confirm the functional group (including finger print region absorbances). 2 . For 1H NMR, label each signal (a, b, c,.... starting from the right (0.0 PPM). Draw the structure of the compound in the spectra and annotate. 13C NMR spectra is provided for information. Annotation of the 13C NMR is not required and will not be graded. For full credit be clear on annotation for all spectra. Providing the correct structure is not sufficient to receive credit.
