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

Question

Quizplus · Accepted Answer

The (M+1)⁺• peak is higher than the molecular ion (M•) peak and results from the presence of one 13C isotope in the molecule. This peak is useful in calculating the number of carbon atoms in the molecule, and can also be used to distinguish between different isotopes of carbon, such as 12C and 13C. Hence, options B and D are correct.
