Question

Acetylene on ozonolysis gives glyoxal.
A.True
B.False

Answer 1

Hint: Acetylene is also known as Ethylene. Ethylene reacts with ozone during the reaction of ozonolysis for the production of acetylene ozonide, but when the further reaction with the hydrolysis process takes place in this reaction in the presence of zinc to form glyoxal.

Complete step by step answer:
Ozonolysis of acetylene with the help of ozone, O atom transferred from the ozone to acetylene. Here the leading to form carbene. Carbene can rearrange to ketene. So, the ozonolysis possesses a complete reaction which is an intensive experiment.
The reaction takes place during the process of ozonolysis. In this reaction, acetylene reacts with ozone and gives the product of acetylene ozonide. When acetyl ozonide reacts in the presence of Zn metal by hydrolysis, it gives us the glyoxal product. So acetylene does not give us a direct product of glyoxal during the ozonolysis. We take glyoxal from the acetylene ozonide. Glyoxal forms by the reaction of hydrolysis.
The reaction of ozonolysis of acetylene is given below,
So the given statement is false.
The correct answer is acetylene reacts with ozone and gives acetylene ozonide.

Hence option B is correct.

Note:
Ozonolysis is the reaction in presence of ozone. This is an organic reaction. Unsaturated bond of hydrocarbons cleaved with ozone. This process follows double and triple bonds to be replaced by double bonds of oxygen. This reaction is used for the unknown structure of alkenes. When we have no idea about the structure of unknown alkene, ozonolysis reaction helps to find the structure of alkenes.
