Identify the important diagnostic peaks from the IR spectrum,
including the cm^-1, and the bond that corresponds to each peak.
List all possible classes of compounds this compound could be. Does
it contain carbon-carbon double or triple bonds?
From the mass spectrum and IR, determine the molecular formula
and calculate the degree of unsaturation.
On the basis of your analysis, propose a structure that fits
all the IR, MS, & CNMR data. Propose a structure that
corresponds to the base...

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 'H NMR Spectra, the integral is given in number of hydrogens (#H) or as a relative ratio. Important coupling constants (J-values) are listed next to the peaks for some examples. For some spectra, an inset (grey box) is also given...
The m/z of the M+ peak of an unknown is 146, and this peak is the base peak (i.e., the tallest peak). (See below mass spectrum of the unknown.) Combustion analysis data indicate 49.03% carbon and 2.74% hydrogen. The IR spectrum and 13C-NMR spectrum of this compound also were obtained and are shown below. Given this information, what is the name of this unknown molecule? MASS SPECTRUM 100 80 60 面 40 20 0.0 120 160 40 80 0.0 m/z...
