Hello,

Another MS spectrum is in the attached file, of C₉H₁₀O. My questions regarding this spectrum are:
I figured out it is some kind of an aromatic ring with a ketone. But can this specrum say whether the substituent is a three carbon ketone (it would be Benzyl methyl ketone) or two substituents- a two carbon ketone and a methyl (that is 1-(4-methylphenyl)- Ethanone)?

Can the MS diffrentiate between the two?

Many thanks!
