Which of the following is true about the (M+1)⁺ ^• peak on the mass spectrum of a hydrocarbon?

Question

Quizplus · Accepted Answer

- Option B is incorrect as there is no such isotope as ¹³C. - Option C is incorrect as (M+1) indicates that the ion has one more mass unit than the molecular ion (M), therefore it has a higher m/z value. - Option A is incorrect as it is not specified which peak is the most abundant in the spectrum. - Option D is correct as the (M+1) peak is useful in determining the number of carbon atoms in the molecule, as it represents the ion with one additional carbon-13 isotope compared to the molecular ion. - Therefore, the correct answer is E, B & D.
