What is the molecular formula of Benzenetriozonide ?
Correct answer: A. C6H6O9
- A. C6H6O9
- B. C6H5O8
- C. C6H5O9
- D. C6H6O6
Explanation
Each of the three ozone molecules adds three oxygen atoms to benzene, so C6H6 + 3O3 gives the ozonide formula C6H6O9. Students may choose C6H6O6 by incorrectly counting only two oxygen atoms per ozone molecule.

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.
