Mass spectrometry is an extremely versatile detection system for GC. However, interfacing an HPLC system to a mass spectrometer is a much more difficult task. Describe the major reasons why it is more difficult to combine HPLC with mass spectrometry than it is to combine GC with mass spectrometry.

Based on this IR what are the relevant peaks?
Can someone explain how to solve this problem? Im having trouble distinguishing between the parent peak and molecular ion peak. When they ask for molecular ion peak, its not the tallest one?

Please interpet this spectrum as far as the major peaks. For example, is the 3438.78 an NH peak or C-O stretch? What about the other main peaks and also the subsitution shown.
Predict and mark all the peaksgiven in the data. You can write aboutyour peak predictionin form of a table or a para graph.
