The hydrolysis of Benzenetrizonide will yield three moles of____________________?
Correct answer: D. Glyoxal
- A. Glyoxime
- B. Benzaldehyde
- C. Glycol
- D. Glyoxal
Explanation
Benzene adds three ozone molecules, one across each of its three double-bond equivalents, and hydrolysis of the ozonide produces 3 moles of glyoxal. Glyoxime is formed when glyoxal reacts further with hydroxylamine, so students may choose it by confusing ozonide hydrolysis with oxime formation.

About Benzene and Aromatic Compounds
Benzene has a planar ring of delocalised π electrons, giving aromatic stability and equal carbon-carbon bond lengths. The topic covers resonance, electrophilic substitution reactions such as nitration, halogenation, sulphonation and Friedel-Crafts reactions, along with substituent effects and the distinction between substitution in benzene and addition in ordinary alkenes.
