_____ mass spectrometry is more likely to reveal the molecular weight of the molecule being analyzed, and ______ mass spectrometry is more likely to reveal structural details of the molecule being analyzed._____ mass spectrometry is considered to be the more sensitive of the two techniques by several orders of magnitude.(CI = chemical-ionization; EI = electron-ionization)

Question

Quizplus · Accepted Answer

CI imparts less energy during the ionization process, allowing greater stability of the ionized molecule.The more stable ionized molecule will last and show less fragmentation.This allows easy determination of the molecule's molecular weight.EI imparts greater energy during ionization, resulting in more instability of the molecular ion, which readily fragments.The greater degree of fragmentation provides greater structural detail.Of the two, CI is considered the more sensitive because of the minimal fragmentation.
