the molecular formula of the compound under analysis is C8H8O2 = Mr of 136
the mass spectrum shows the peak at 91 to be the most stable. I'm supposed to obtain structures representing the peak at 91 as well as at 118 and 65
The Attempt at a Solution
I represented 91 as the benzene ring with H-C(-H) attached
@ 118 H-C-C(=O) is attached
I'm having trouble getting the structure at 65
C8H8O2 would be represented as the benzene ring with H-C(-H)-C(=O)-O-H attached.
The only way i'm seeing to obtain 65 is if i remove the attached group from C8H8O2 along with a C from the benzene ring. Is this even possible? Because I know the benzene ring is very stable...
