Which of the following is true about the molecular weight and the M⁺ ^. m/z value for the following compound?

Question

Quizplus · Accepted Answer

The M⁺F1F1F1S1^F1F1F10-m/z value indicates the ions formed by the compound when it is fragmented by mass spectrometry. The m/z value can be calculated by summing up the masses of the fragment ions. The compound has an odd molecular weight because it has an odd number of nitrogen atoms (from the given compound name). To get the m/z value, we need to consider the ions with the highest abundance. In this case, they are the (M-1)+ and (M-2)+ ions, which have masses of 120 and 119 respectively. Adding the mass of one hydrogen ion (1 Da) gives us the corresponding m/z values of 121 and 120. Therefore, the correct answer is B - odd molecular weight, m/z-121.
