Questions & Step-by-Step Solutions

What is the main product of the reaction of ethene with ozone followed by zinc reduction?
Correct Answer: Acetaldehyde
  • Step 1: Start with ethene, which is a simple alkene with the formula C2H4.
  • Step 2: React ethene with ozone (O3) in a process called ozonolysis. This breaks the double bond in ethene and forms an ozonide intermediate.
  • Step 3: The ozonide is unstable and is then treated with zinc (Zn) in a reduction step.
  • Step 4: During the reduction with zinc, the ozonide is converted into carbonyl compounds.
  • Step 5: The main product formed from this reaction is acetaldehyde, which has the formula C2H4O.
