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 = C₇H₇I

Answer

The peak at m/z 32 indicates the presence of sulfur.
Molecular formula = C₇H₆SH

Answer

The peak at m/z 37 indicates the presence of chlorine.
Molecular formula = C₇H₇Cl

Answer

The peak at m/z 81 indicates the presence of bromine.
Molecular formula = C₇H₇Br
