Organic Chemistry 1 Lab Fall 2019 Spectral Set 2 Due 10/29 - 10/31/2019, during regular lab time. For each set of spectra, label the major IR absorptions, deduce a workable formula, and calculate the DBE for that formula. Then using the splitting patterns and integrations, determine the structure of the molecule responsible for the spectra. Be sure to label each NMR signal like we did in class. S = singlet, d = doublet, t= triplet, q#quartet, p = pentet, n=nonet,...
