Write down the products of ozonolysis of 1, 2 - dimethylbenzene (o -xylene). How does the result support Kekules structure for benzene?

Red shows the cleaved bonds
Consider, if this was say, the Dewar structure, you would not end up with these products
Whats a dewar structure?
I understood the problem easily but I don't understand this image
Was this also one of the structures which was proposed for benzene?
Or am I getting something wrong here
Correct
Some of these look real nonsensical now, but consider, these people did not have even the vaguest idea of what proton NMR was.
what will be the products in the other resonating struc of benzene
atleast prismane is an actual compound
Just cleave, put an O on each cleaved double bond, and you can check.
It's not going to be very different
You get 2 mols of one compound and 1 mol of another, always
this raises the question, what happens when you attempt to cleave a real compound like this, i.e. a resonance hybrid
its not like the compound exists in one form or the other and alternates its always the hybrid
