Which of the following is (are) formed by ozonolysis of the following alkyne?

Question

Quizplus · Accepted Answer

The ozonolysis of an alkyne results in the formation of ketones and/or carboxylic acids.

I. Propanone (ketone) is formed by the oxidative cleavage of the triple bond in the alkyne. This is a common product of ozonolysis of alkynes.

II. Ethanal (aldehyde) is formed from one of the resulting carbonyl groups in propanone by oxidative cleavage. This is also a common product of ozonolysis.

III. Methanoic acid (carboxylic acid) is formed by the oxidative cleavage of the other carbonyl group in propanone. This is less common than the formation of ketones and aldehydes, but it is still a possible product.

IV. Carbon dioxide and water are formed by the oxidative cleavage of both carbonyl groups in propanone. This is a less common reaction and requires certain conditions to occur.
