Question
Which alkyne yields propanoic acid as the only product upon treatment with ozone followed by hydrolysis?
Correct Answer
Option D is the correct answer.
Detailed Explanation
3-Hexyne (CH3CH2-C≡C-CH2CH3) on ozonolysis gives propanoic acid (CH3CH2COOH) as the only product. Both carbons of the triple bond bear ethyl groups, which are oxidized to propanoic acid.
Hint
