Why does bromine produces M⁺• and (M+2)⁺• peaks of equal intensity on a mass spectrum?

Question

Quizplus · Accepted Answer

The two isotopes of bromine that contribute to the (M+2) peak have almost equal natural abundance, which is why the peak appears with equal intensity to the M peak. Option A is incorrect because it suggests that one isotope of bromine has a higher natural abundance than the other, which is not true. Option C is also incorrect as it is the same as option A. Option D is not a valid choice as there is a correct answer.
