An analytical spectroscopic technique that is used for the structural determination of the organic compound using the fragmentation of ionic organic compounds (in the vapor phase) and arranging them in the charge-to-mass (m/z) ratio in the presence of a magnetic field is called mass spectroscopy. The molecular ion peak is the peak with the highest mass-to-charge (m/z) ratio.The base peak is the tallest peak with the highest intensity (100%) and the rest of the peaks are observed relative to it.Molecule A:The molecular ion of the molecule A will be observed at m/z 86.Fragmentation of the alpha bond to the carbonyl group leads to two peaks, m/z 57 and m/z 29.Spectrum 5 matches the fragmentation discussed above. So, Molecule A corresponds to Spectrum 5.Base peak is at m/z 57.Molecule E:The molecular ion of the molecule B will be observed at m/z 88.Fragmenting the molecule further from the right side one by one will lead to peaks at m/z 88, m/z 73, m/z 57, m/z 43, m/z 29, as indicated below.Spectrum 1 matches the fragmentation discussed above. So, molecule E corresponds to spectrum 1.Base peak is at m/z 43.Molecule G:The molecular ion of the molecule G will be observed at m/z 87.Fragmenting the molecule further from the right side one by one will lead to peaks at m/z 87, m/z 71, m/z 57, m/z 42, m/z 29, as indicated below.Out of the given spectra, spectra 1 closely resembles the fragmentation discussed above.The base peak is at m/z 42.Molecule H:The molecular ion of the molecule H will be observed at m/z 87.Fragmenting the molecule further from the right side one by one will lead to peaks at m/z 87, m/z 72, m/z 57, m/z 44, m/z 29, as indicated below.Out of the given spectra, spectra 1 closely resemble the fragmentation discussed above.The base peak is at m/z 44.Molecule A: Spectrum 5 (base peak m/z 57)Molecule E: Spectrum 1 (base peak m/z 43)Molecule G: Similar to Spectrum 1 (base peak m/z 42)Molecule H: Similar to Spectrum 1 (base peak m/z 44)
