Singular Positive Charge 2 of 7 What can occur to the molecules if hit with too much energy? Fragmentation 3 of 7 What is fragmentation? When molecular ions are split into smaller parts due to the breaking of a bond, one fragment as a singular positive charge the other is neutral 4 of 7 How can you identify the molecular ion? It is the peak the furthest to the right, it has the largest mass/charge ratio 5 of 7 What is another name for the tallest peak on a mass spectrometer? The base peak 6 of 7 How do you represent fragmentation equations? Molecular Ion (single positive charge) into Fragment ion (single positive charge) + Neutral fragment 7 of 7
