23.(10 pts) The following IR and 'H NMR spectra are for a compound with the formula C5H9Cl (on the next page). The integrations for the NMR are shown above the spectrum. The two closely spaced peaks at about 1.7ppm are 2 singlets (not a doublet like you might think), and the small little peak just to the right of those 2 peaks is an impurity. Determine the structure of the compound. Show your work. Inteoratione
