Question

Consider the following mass spectrum:Identify which distinctive feature indicates the presence of sulfur, chlorine, bromine, iodine, or nitrogen. Try to determine the molecular formula of the compound.

Accepted Answer

The peak at m/z 127 and a difference of 127 between m/z 218 and m/z 91 indicates the presence of iodine. Molecular formula = $$C_{7}$H_{7}I$$

Answer

The peak at m/z 32 indicates the presence of sulfur. Molecular formula = $$C_{7}$H_{6}SH$$

Answer

The peak at m/z 37 indicates the presence of chlorine. Molecular formula = $$C_{7}$H_{7}Cl$$

Answer

The peak at m/z 81 indicates the presence of bromine. Molecular formula = $$C_{7}$H_{7}Br$$
