NMR Help please!
Based on the molecular formula and the UN/DBE you calculated, check all the functional group that could be present in compound B? Examine the IR spectrum provided for Compound B. The peaks below 1500 cannot be used to make any structural assignments because they are i fingerprint region. There are the two important peaks in this IR spectrum, What is each peak most likely due to? Earlier, using the molecular formula and the UN/BE, you came up...

A suggested approach to solving structures is provided for your benefit (this is by no means comprehensive) Since the molecular formula is provided for each problem students will use the formula provided below where C = #carbons, N = # of nitrogen's, H = #hydrogens, and X = # of halogens to find the Unsaturation index (U). U /2C+N Examine the IR spectrum for the presence or absence of groups with diagnostic absorption bands e.g. carbonyl groups, hydroxyl groups, amines...
