What are the products formed when CH3–C≡C–CH2–CH3 undergoes ozonolysis?

1. CH3–CO and hydrogen peroxide
2. CH3CH2CO
3. CH3COOH and CH3CH2COOH
4. Acetic acid and propionic acid

Correct answer: CH3COOH and CH3CH2COOH

Solution

Ozonolysis of alkynes cleaves the triple bond, forming carboxylic acids. Here, CH3–C≡C–CH2–CH3 produces CH3COOH (acetic acid) and CH3CH2COOH (propionic acid).
