How to Convert Propene to Ethene

Step-1:

Propene reacts with HBr in presence of Hydrogen peroxide(H₂O₂) and we get 1-bromo propane(CH₃-CH₂-CH₂-Br).

Step-2:

1-bromo propane (CH₃-CH₂-CH₂-Br) reacts with aqueous KOH and we get propanol(CH₃-CH₂-CH₂-OH).

Step-3:

Propanol(CH₃-CH₂-CH₂-OH) reacts with K₂Cr₂O₇ in presence of H₂SO₄ and we get propanal(CH₃-CH₃CHO).

Step-4:

Propanal(CH₃-CH₃CHO) again reacts with K₂Cr₂O₇ in presence of H₂SO₄ and we get propanoic acid(CH₃CH₂COOH).

Step-5:

Propanoic acid(CH₃CH₂COOH) reacts with Conc.NH₃ and we get ammonium propanoate(CH₃CH₂COONH₄).

Step-6:

Ammonium propanoate(CH₃CH₂COONH₄) is heated and we get propanamide (CH₃-CH₂CONH₂).

Step-7:

Propanamide[CH₃-CH₂CONH₂) reacts withBr₂ in presnce of KOH and we get ethyl amine(CH₃-CH₂NH₂).

Step-8:

Ethyl amine(CH₃-CH₂NH₂) reacts with NaNO₂+HCl and we get ethanol(CH₃CH₂OH).

Step-9:

Ethanol(CH₃CH₂OH) reacts with PCl₅ and we get chloro ethane(CH₃-CH₂Cl).

Step-10:
Chloro ethane(CH₃-CH₂Cl) alcoholic KOH and we get ethene(CH₂=CH₂).
