Mass Spectroscopy
Cards in this deck (6)
- 1Describe how mass spectroscopy worksThe molecules in the sample are bombarded with electrons and a molecular ion, M⁺, is formed when the bombarding electrons remove an electron from the molecule.
- 2Given the mass spectrum of a compound, how can the relative molecular mass be found?Look at the molecular ion peak (the M peak). This is the peak with the highest mass/charge ratio, ignoring any M+1 peak. This is the molecular mass of the compound.
- 3Complete the sentences: The bombarding electrons make some of the molecular ions break up into _____________. The fragments that are ions show up on the _______ __________, making a __________________ pattern.The bombarding electrons make some of the molecular ions break up into FRAGMENTS The fragments that are ions show up on the MASS SPECTRUM, making a FRAGMENTATION pattern.
- 4Describe the fragmentation of CH₃CH₂CH₃⁺
- 5Draw the fragments that are produced from CH₃COCH₃
- 6Draw the fragments that are produced from CH₃CH₂COOH
