Products of the following reaction: CH3C≡C−CH2CH3 (1) O3 (2) Hydrolysis → ...... are:

1. CH3COOH + CO2
2. CH3COOH + HOOC−CH2CH3
3. CH3CHO + CH3CH2CHO
4. CH3COOH + CH3COOCH3

Correct answer: CH3COOH + CO2

Solution

Ozonolysis of an alkyne cleaves the triple bond, producing carboxylic acids. Here, CH3C≡C−CH2CH3 forms CH3COOH and CO2 upon ozonolysis and hydrolysis.
