Consider the modified anti-tumor intermediate below and answer the following:   How many acyl groups are in the molecule above? [acyl4] (enter number only) Based on what we have observed so far, how many H atoms would be added to the molecular formula if it were treated with normal hydrogenation conditions (H2, metal)? [H8] (enter number only) How many free carboxylate groups are formed after treatment with saponification conditions? [carb2](Number only) Considering only the diasterotopic Hs, which letter indicates the position of the proton that is the most downfield in the 1H NMR? [nmrc] (enter letter only) Considering only the methine Hs, which letter indicates the position of the proton that is the most downfield in the 1H NMR? [nmre] (enter letter only) Which letter indicates the position of the proton signal that is the most upfield in the 1H NMR? [nmrg]

Consider the spectrum and answer the following: (note: the unlabeled signal at ~6ppm is a multiplet) a) Which molecule agrees with the provided 1H NMR spectrum (below)? [nmr] b) Which molecule should have the most deshielded non-aromatic singlet? [nmr1] c) What will be the splitting pattern of the most deshielded non-aromatic signal in molecule 1? [t1] d) Which molecule after undergoing Friedel-Crafts methylation provides a molecular formula of C10H10O but does not show any change in the total number of signals in the 1H NMR, but does show a change in chemical shifts? [FC]
