The diene shown is subjected to ozonolysis with reductive work-up. Which statements are correct?

  1. AThree distinct carbonyl compounds are formed.
  2. BOne product contains both an aldehyde group and a ketone group.
  3. CPropanone is one of the products.
  4. DWith work-up a diketone would be one of the products.

Answer: A, B, C

The compound shown is 2,6-dimethylhepta-1,5-diene. Reductive cleavage gives methanal, 4-oxopentanal (a keto-aldehyde) and propanone: three compounds. With the aldehyde groups are oxidised, so 4-oxopentanoic acid (a keto-acid, not a diketone) forms. Statements 1, 2 and 3 are correct and 4 is not.
