1. For each of the following statements, indicate whether they are true of false. ⚫ mass spectrometry allows us to determine the molar mass and molecular formula of an organic compound, as well as some of its structural features. • mass spectrometry generally allows us to determine the precise structure of an organic compound. ⚫ when a molecular ion undergoes fragmentation, weak bonds break in preference to strong bonds. • when a molecular ion undergoes fragmentation, bonds that break to form less stable fragments break in preference to those that form more stable fragments. • the only way to ionize an organic compound is by passing it through a beam of 70 eV electrons. • mass spectrometry is one of several techniques that are routinely used for the determination of the structure of an unknown organic compound. • mass spectrometry can be coupled with gas chromatography to afford a very valuable separation/analysis technique. • chlorides and bromides are dead easy to spot because of the characteristic M and M+2 isotopic patterns.
