Which of the following structures will give a base peak of 43 in mass spectrometry? B)CH₃CH₂CH₂CH₂CH₂CH₃ E)none of the above

Question

Quizplus · Accepted Answer

Base peak in mass spectrometry is the most intense peak in the spectrum. The structure that generates the base peak of 43 will have a fragment with a mass of 43. Examining the given structures, only structure C has a possible fragmentation pattern that could generate a peak with a mass of 43. The fragment that would produce a peak of 43 is CH2=N-NH2+. Hence, option C is the correct answer.

Which of the Following Structures Will Give a Base Peak
