1.	Of the following compounds, whose ozonolysis proves the Kekule structure of benzene?A. a.BenzeneB. b.TolueneC. c.o-XyleneD. d.p-Xylene
Answer» Correct Answer - C o-Xylene on ozonolysis gives glyoxal: methylglyoxal: dimethyl glyoxal in the ratio `3:2:1`, which proves the existance of resonance in benzene and hence proves the Kekule structure of benzene. So the answer is `(c )`.
