Which of the following is always true about the base peak in a mass spectrum?

Question

Quizplus · Accepted Answer

The base peak in a mass spectrum corresponds to the most abundant ion, which is the ion with the highest relative abundance in the spectrum. This may not always be the molecular ion (A) or the ion with the lowest m/z( C), as the most abundant ion may be a fragment ion that has a higher relative abundance than the molecular ion. Therefore, B is the only choice that is always true.
