Interpretation Introduction

Interpretation:

If the natural abundance of 13C is 1.10%, the relative heights of M+ and M+1peaks in the mass spectrum of benzene are to be given.

Concept introduction:

Mass spectrum of compounds contains in addition to the molecular ion peak (M+) a small peak at M+1. This peak arises due to the different isotopes of the atoms present in the molecule. The heights of M+ and M+1peaks in the mass spectrum of a compound will be in proportion to the percentage of the different isotopes of atoms present in the molecule.

To give:

The relative heights of M+ and M+1peaks in the mass spectrum of benzene if the natural abundance of 13C is 1.10%.

In the mass spectrum of an unknown organic compound, the molecular ion had a relative abundance of 19.0 while the M+1 had a relative abundance of 1.5. Estimate the number of carbons in the molecule. 1 4 7 2 LO 5 8 carbons 3 6 9 X C
If the mass spectrum of a sample has a 7.7% M+1 peak compared to a 100% M+ peak, how many carbon atoms are we then likely to have in our chemical formula?
Bromine has two naturally occuring isotopes, Br-79 and Br-81, approximately 50% of each.  Bromomethane will contain approximately 50% Br-79 and 50% Br-81.   The mass spectrum peak for methane containing Br-79 will be referred to as the M+ (molecular ion) peak, and the peak for Br-81 will be called the M+2 peak, as Br-81 weighs two more amu than Br-79. What will be the locations of the two bromomethane peaks on the mass spectrum and what will be the approximate ratio of their heights?
