How many carbon atoms are present in a molecule which gives an M+1 peak that is 11.48% of the intensity of the molecular ion?

Question

Quizplus · Accepted Answer

The M+1 peak is due to the presence of the carbon-13 isotope. The intensity of the M+1 peak relative to the molecular ion peak is approximately 1.1% per carbon atom. Therefore, if the M+1 peak is 11.48% of the molecular ion peak, the molecule likely contains about 11 carbon atoms (11.48 / 1.1 ≈ 11).
