Question

Convert 1,2 dibromoethane to ethene

Answer 1

Answer:

Br - CH₂ - CH₂ -Br + Zn -----------> CH₂ = CH₂ + ZnBr₂

Explanation:

Change Br with Cl for dichloroethane.

Answer 2

• 1,2-dibromoethane is a single-bonded saturated carbon compound.

• Ethene (CH₂=CH₂) is a double-bonded unsaturated carbon compound.
• 1,2-dibromoethane can be converted into ethene by reaction with aqueous KOH.
• Aqueous KOH converts 1,2 dibromoethane to ethene.
• $Br-CH2-CH2-Br --> CH2=CH-Br$
