In the stretching region of the spectrum, identify as many IR peaks as possible that are consistent with the molecular formula. List the wavenumber of each identifiable peak and the type of bond or structural grouping to which it corresponds. Draw the structures of all possible molecules that are consistent with both the molecular formula and the stretching frequencies present in the IR spectrum. On the basis of all frequencies, both stretching and bending, ) state which structure(s) can be...
