How many moles of Glyoxal (CHO-CHO), Methylglyoxal, and Dimethylglyoxal are theoretically produced u — Aromatic Hydrocarbons Chemistry Question
Question
How many moles of Glyoxal (CHO-CHO), Methylglyoxal, and Dimethylglyoxal are theoretically produced upon the vigorous ozonolysis of one mole of o-xylene, proving its resonance hybrid nature?
Answer: C
💡 Solution & Explanation
If localized Kekule bonds existed, o-xylene would have two stationary forms giving specific products. Because it is a resonance hybrid, the ozonolysis mixture contains fragments from both theoretical Kekule structures: Glyoxal, Methylglyoxal, and Dimethylglyoxal.
