Description: Shown below is an EI-MS spectrum for t-butyl chloride. 1) Clearly label the base peak in the spectrum. Draw the structure of the fragment the base peak corresponds to. 2) Is there a molecular ion present in the spectrum? If so, label the peak that corresponds to the molecular ion. 3) Is there any evidence that the following EI-MS spectrum represents a chlorine containing compound? If so, label the necessary peaks and explain briefly why there is sufficient evidence...
