Question

NMR question- I'm having issues with page 2 where I'm supposed to assign the hnmr signal but I came up with only 5 signals not 6 and they aren't lining up with my molecule.. I'm not sure maybe the molecule is wrong but I don't think so - help

M+-114 M+= 114 amu a) The mass spectrum of the unknown molecule is shown above Using only the mass spectrum shown above, determine all the likely possible chemical formulas assume that the molecule contains only C & H or only C, H, & O). What is the degree of unsaturation in each of the possible structures? l6 llo ㄚㄐ 3000 1500 1000 3500 Wavenumbers (cm-I) b) Identify the major functional groups of the molecule in the IR spectrum shown above by labeling the peaks on the graph. Also, identify which important peaks are absent.
