Question

An organic compound T' reacts with ozone to give addition product which on hydrolysis in presence of zinc dust gives formaldehyde. Suggest the structure of A with necessary chemical
reaction.
​

Answer 1

Explanation:

Ozonolysis is an organic reaction where the unsaturated bonds of alkenes, alkynes, or azo compounds are cleaved with ozone. Alkenes and alkynes form organic compounds in which the multiple carbon–carbon bond has been replaced by a carbonyl group while azo compounds form nitrosamines. The outcome of the reaction depends on the type of multiple bond being oxidized and the work-up conditions.

Answer 2

Answer:

The organic compound "T" is CH₂=CH₂(suggested structure).

Explanation:

First, let's understand what is ozonolysis.

• An extremely reactive allotrope of oxygen is ozone.
• Alkenes and alkynes undergo oxidative cleaving as a result of ozone's reaction with them.
• The necessary carbonyl product is produced by substituting carbon-oxygen double bonds for the carbon-carbon triple bonds.
• One of the products of ozonolysis is formaldehyde, which is produced when one vinyl (or ethenyl) group is present.
• HCHO is produced via ozonolysis of CH₂=CH₂.

The reaction will proceed as follows,

$\mathrm{CH_2=CH_2+O_3\xrightarrow{Zn/H_2O}ZnO+2HCHO}$

So, the suggested structure of the organic compound is ethene(alkene).
