4Question 4.
True or False: A mass spectrum provides absolute identification of compounds.
- True
- False
Show hintHide hint
Consider the role of isomers in identification.
Question 5.
A mass spectrometer identifies a compound with a mass spectrum showing peaks at m/z 78, 77, and 51. Compare this to possible compounds from the library just with these fragments, what does this indicate about the possible identity?
Show hintHide hint
Think about the common structures of organic compounds and their typical mass peaks.
Question 6.
Explain the process of setting up a library for mass spectra comparison. What key details must be included?
Show hintHide hint
Consider what information is crucial for matching spectra.
