OzonolysisMediumQuestion 770006

Question

Ozonolysis of CH₃−CH=CH−CH₃ (but-2-ene) gives:
  1. A
    2 mol CH₃CHO (ethanal)
    Correct
  2. B
    CH₃COCH₃ + HCHO
  3. C
    2 mol CH₃CH₂OH
  4. D
    CO₂ + H₂O

Correct answer

2 mol CH₃CHO (ethanal)

Explanation

Ozonolysis breaks the C=C double bond. But-2-ene: CH₃−CH=CH−CH₃ → CH₃CHO + CH₃CHO. Each carbon of the double bond gets an oxygen (=O), giving two ethanal molecules.
