Question

Consider the following mass spectrum:

Mass spectrum showing peaks indicating sulfur, chlorine, bromine, iodine, and nitrogen presence.

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
