Hello fellow H. sapiens!
I am analyzing a GC printout of an organic layer that contains several organic compounds which were byproducts of a reaction. It contains four distinct peaks, but here is the problem:
The GC instrument is pretty crappy, so certain chemicals, such as ortho-xylene, can produce two adjacent signals. I asked a friend of mine and he said that its because there are two resonance forms. Although it is just one chemical on average, the bonding between carbon 1 and carbon 2 is sometimes a single bond and sometimes a double bond. But I disagree to a certain extent...
Could resonance contributors of the same chemical yield two adjacent signals due to the two "distinct" resonance forms? My understanding of resonance is that a molecule does not exist is a certain resonance form at a given point in time, but rather, all exist to some degree simultaneously in an electron delocalization event.
So who is right? What could cause two adjacent GC signals of the same chemical?
