    Alkynes do not undergo ozonolysis like alkenes. Why?

    Answer:

                    Alkynes have a triple bond \[(C\equiv C)\] in their molecules. Reaction with ozone results in the formation of an ozonide. Now, treatment with zinc dust and water does not cleave the triple bond completely. Therefore, a mixture of two carbonyl compounds is not formed. In other words, alkynes do not undergo complete cleavage in the same way as alkenes.
