Question

Benzene reacts with ozone (not hydrolysis), the product formed is.
a) Benzene triozonide.
b) Glyoxal.
c) Ethene diol.
d) All of them.

Answer 1

Hint: We realize that Ozonolysis is a natural response where the unsaturated obligations of alkenes, alkynes, or azo mixtures are severed with ozone. Alkenes and alkynes structure natural mixtures in which the different carbon–carbon bond has been supplanted by a carbonyl group while azo mixtures structure nitrosamines. The result of the response relies upon the kind of numerous bonds being oxidized and the stir up condition.

Complete answer:
We have to remember that ozonolysis is the cleavage of an alkene or alkyne with ozone to shape natural mixtures wherein the numerous carbon–carbon bonds have been supplanted by a twofold cling to oxygen. The ozonolysis of benzene structures Glyoxal through the development of benzene Triozonide as a middle. Subsequently no hydrolysis occurs so benzene Triozonide appears as a product. Henceforth, Option A is the right answer
The reaction is,

Ozonolysis instrument continues by means of an oxidative cleavage response. The ozone breaks the carbon pi bond as well as the carbon-carbon sigma bond. It includes the assault of ozone on the offered reactant to shape an ozonide. To kill the oxygen in this middle stage, zinc dust is utilized (since it structures zinc oxide with the oxygen). The end result differs depending on the kind of reactant and the workup. Given underneath is delineation portraying the overall system of the ozonolysis response for alkenes and alkynes.

Note:
We know that Alkenes can be oxidized with ozone to shape alcohols, aldehydes or ketones, or carboxylic acids. In a run of the mill method, ozone is raised through an answer of the alkene in methanol at \[ - 78^\circ C\] until the solution takes on a trademark blue tone, which is expected to be unreacted ozone. This demonstrates total utilization of the alkene. Then again, different synthetic compounds can be utilized as pointers of this endpoint by distinguishing the presence of ozone. In the event that ozonolysis is performed by percolating a surge of ozone-enhanced oxygen through the response blend, the gas those air pockets out can be coordinated through a potassium iodide solution. At the point when the solution has quit retaining ozone, the ozone in the air pockets oxidizes the iodide to iodine, which can without much of a stretch be seen by its violet color.
