Which of the following m/z values correspond to the molecular ion peak of the following compound?

Question

Quizplus · Accepted Answer

The molecular ion peak corresponds to the mass of the intact molecule, which is the sum of the masses of all the atoms in the molecule. The molecular formula of the compound in this question is not given, so we cannot calculate the exact mass. However, we can make an estimate based on the given m/z values. The molecular ion peak is typically the highest m/z value observed in the mass spectrum, and it corresponds to the ion with a single charge that has lost one electron (M+·). Based on the given m/z values, the molecular ion peak is most likely to be 136, which is the only value that is within 1 m/z unit of the other peaks given (135 and 137). Therefore, the best choice is D.
