Alpha cleavage of the following compound would produce fragments at m/z = 43 and m/z = 119.

Question

Quizplus · Accepted Answer

Alpha cleavage is a type of fragmentation in mass spectrometry where a bond adjacent to a carbonyl group breaks. The resulting fragment has a positive charge on the carbonyl carbon and a lone pair on the adjacent atom. In this case, the fragment at m/z = 119 likely contains the carbonyl group, and the fragment at m/z = 43 likely contains the remaining portion of the molecule. Therefore, it is true that alpha cleavage of the compound would produce fragments at m/z = 43 and m/z = 119.
