Question

Benzene reacts with ozone to give a triozonide which on treatment with zn/h2o yields

Answer 1

Answer - Glyoxal

Benzene reacts with Ozone to give a Benzene trizonide,
It further reacted with zinc and water at very high temperature to give Glyoxal.

Reaction Involved :- Refer to the attachment for better understanding 

__________________________

C₆H₆ + 3O₂ ------------→ Benzene Triozonide

Benzene Triozonide ----(3H₂O/Zn)---→  3CHO-CHO + 3H₂O₂
__________________________

Explanation :- Here Benzene reacts with ozone and produce Benzene Triozonide , Further Benzene triozonide is treated with Zn /H₂O and Produce Glyoxal and release H₂O₂.
Here we observe that ozonolysis of benzene forms Glyoxal by the production of benzene Triozonide as an intermediate product
