Vedclass · Answer

(D) $o$-xylene is a resonance hybrid of two Kekulé structures. Ozonolysis of these structures yields glyoxal $(CHO-CHO)$,methylglyoxal $(CH_3-CO-CHO)$,and dimethylglyoxal $(CH_3-CO-CO-CH_3)$. The product $CH_3-CO-CO-CHO$ cannot be formed because the benzene ring breaks into three $2$-carbon fragments during ozonolysis.

Which of the following products cannot be obtained in the ozonolysis of $o$-xylene?
