Answer

Upon ozonolysis, this alkene would yield two products: one molecule of ethanal (acetaldehyde) and one molecule of propanone (acetone).

Step 2

B CH₃CH=CH₂

Answer

This alkene can be ozonized to yield only one product, which is propanone.

Step 3

C CH₃C=CH₂

Answer

This alkene would produce a mixture of products; however, it would not give a mixture of ethanal and propanone.

Step 4

D CH₃CH=CH₂
