5. Mass Spectrometry and IR Spectroscopy (-- points). The mass spectrum and Infra-red spectrum of a compound of unknown structure are shown below. The compound has no alkene functionality and no chiral carbons. a. Assign the peaks the following peaks in the mass spectrum: molecular ion, base peak, peak b. Assign the major peaks in the IR spectrum c. Propose a structure for the compound based on the data given; draw your structure in the box on the next page.
Expert Answer
a. Assigning the peaks in the mass spectrum:Molecular ion peak: The peak at m/z 100 corresponds to the molecular ion (M), representing the parent molecule's mass.Base peak: The highest peak in the spectrum is not specified in the question. Without the specific m/z value, we cannot assign the base peak accurately.M+1 peak: Since the compound has no chiral carbons, the M+1 peak will be absent in this case.
