Question

Convert propene to ethanal.In
3-4 steps​

Answer 1

Answer:

Propene on reaction with ozone and water gives acetaldehyde, which further reacts with

$PCl_5$gives 1,1-dichloroethane which loses 2 moles of HCl to form acetylene(ethyne).

Answer 2

• Propene reacts with ozone gas to form an intermediate type complex propene ozonide.
• This propene ozonide reacts with zinc and water to form ethanal along with methanal.
• Here zinc acts as a reducing agent and reduced propene ozonide complex. It breaks down the bonds of propene ozonide to form the desired product ethanal along with methanal.
