Question

Information: Each spectra below was obtained from a pure compound. Mass Spectrum parent peaks (M) are listed for all examples. IR peaks listed are strong (s) unless otherwise indicated for signals above 1500 cm 1H NMR Spectra, the integral is given in number of hydrogens (#H) or as a relative ratio. Important coupling constants U-values! are listed next to the peaks for some examples. For some spectra, an inset (grey box) is also given showing a "zoom-in" on an important part of the spectrum. Mass Spectrometry (not shown): [M)-200 (50%), [M+2]-202 (100%).IM+4-204 (50%) m/z Infrared Spectroscopy (not shown): 2968, 2906 cm H Nuclear Magnetic Resonance. quin 0 2H PPM 13C Nuclear Magnetic Resonance. 35 30 25 PPM
