Riddle ! [only for MS lovers]
« on: June 15, 2009, 03:47:58 PM »
Hey folks,

i've been hitting my head against the wall for couple of hours now
and decided to post it here, hoping you guys can help.

I'm trying to find out what are the structures for the following peaks: m/e=122 and m/e=68.

can't think of anything that fits...  ???  ???

Ah yes, the deduce the contents of a pipe bomb from the pieces. In grad school, our library had several books in which the fragmentation and rearrangement processes were deduced. I'll just give some pieces that might fit from ChemDraw.

I am expecting the cyclopropane opens and then I don't know.

Well, from the isotopic pattern m/z 122 contains at least one Cl, while m/z 68 contains none. I guess that's a start.
