Which of the following characterizes the unusually intense peak of alkyl chlorides in MS spectrometry?

Question

Quizplus · Accepted Answer

The unusually intense peak of alkyl chlorides in MS spectrometry is the M + 2 peak, which is caused by the presence of chlorine-37 (which has an atomic mass of 36.965) instead of chlorine-35 (which has an atomic mass of 34.969). This is because the peak corresponding to the molecular ion (M) is often not observed in alkyl chlorides due to their fragmentation during ionization. The M + 1 peak (which is caused by the presence of one extra carbon-13 isotope) may also be present to a lesser extent, but it is usually less intense than the M + 2 peak. The base peak represents the most abundant ion in the spectrum, while the parent peak represents the intact molecular ion.
