Which of the following statements regarding mass spectrometry is wrong?
  • a)
    In a normal mass spectrometer, electron impact causes a molecule to lose an electron and become a molecular radical cation which decomposes into fragment cations and radicals.
  • b)
    Only cations can be detected by a normal mass spectrometer.
  • c)
    A compound whose molecules contain just one bromine atom shows two molecular ion peaks of similar intensity, one at +1 and one at -1 of the average m/z value.
  • d)
    Molecular ion peaks always have even-numbered values of m/z.
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
Which of the following statements regarding mass spectrometry is wrong...
The molecular mass of a molecule containing one nitrogen atom, for example, is an odd number of atomic mass units, so its molecular ion peak has an odd numbered m/z ratio; statement (d) is wrong.
