Describe various oxidation reactions of benzene.

(N/A) Baeyer's test: Benzene does not undergo Baeyer's reaction due to its characteristic stability. It does not show an unsaturation test and does not decolorize $KMnO_{4}$ solution.
$\text{Benzene} + \text{dilute, cold } KMnO_{4} \longrightarrow \text{No reaction}$
$(b)$ Complete combustion of benzene: The combustion of benzene is carried out in a burner in the presence of air. It burns with a sooty flame and produces $CO_{2}$ and $H_{2}O$.
$C_{6}H_{6} + \frac{15}{2} O_{2} \stackrel{\Delta}{\longrightarrow} 6CO_{2} + 3H_{2}O_{(g)}$
$(c)$ Reductive ozonolysis of benzene: Benzene reacts with three molecules of ozone to form benzene triozonide. This confirms the presence of three double bonds in benzene. Benzene triozonide,upon reductive cleavage in the presence of $(Zn + H_{2}O)$,yields three molecules of glyoxal.
