Which of the following will produce M⁺ ^. and (M+2)⁺ ^. peaks of equal intensity?

Question

Quizplus · Accepted Answer

The presence of (M+2) peaks of equal intensity indicates the presence of two isotopes of the same element, one of which has one more neutron (M+2) than the other (M). Chlorine and bromine have two isotopes with nearly equal abundance and the same difference in mass, which would produce (M+2) peaks of equal intensity. Nitrogen and oxygen also have isotopes with a mass difference of 2, but the (M+2) peak would not be of equal intensity. Therefore, the best choice(s) is C, bromine.
