Question
Alkynes cleave in the presence of ozone to give
Correct Answer
Option D is the correct answer.
Detailed Explanation
Ozonolysis of alkynes (followed by hydrolysis) cleaves the triple bond to yield two carboxylic acid molecules. For internal alkynes, both sides become acids; for terminal alkynes, one product is carbon dioxide.
Hint
Ozonolysis of alkenes gives carbonyls; ozonolysis of alkynes gives a more oxidized product.
