C₂H₅Br + KOH --> C₂H₄ +KBr + H₂O
C₂H₄ + Br₂ --> C₂H₄Br₂

Answer 2

Reaction Steps:

The reaction steps for the conversion of C2H6 to C2H4Br2 can be summarized as follows:

1. Conversion of C2H6 to C2H5Br: - C2H6 (ethane) reacts with HBr (hydrogen bromide) in the presence of heat or light to form C2H5Br (bromoethane). - The reaction can be represented by the following equation: C2H6 + HBr → C2H5Br + H2.

2. Conversion of C2H5Br to C2H4: - C2H5Br (bromoethane) undergoes a dehydrohalogenation reaction to form C2H4 (ethylene). - The reaction is typically carried out in the presence of a strong base, such as sodium hydroxide (NaOH) or potassium hydroxide (KOH). - The reaction can be represented by the following equation: C2H5Br + KOH → C2H4 + KBr + H2O.

3. Conversion of C2H4 to C2H4Br2: - C2H4 (ethylene) reacts with Br2 (bromine) in the presence of a catalyst, such as FeBr3 (iron(III) bromide), to form C2H4Br2 (1,2-dibromoethane). - The reaction is an addition reaction where the bromine atoms add across the double bond of ethylene. - The reaction can be represented by the following equation: C2H4 + Br2 → C2H4Br2.

Summary of Reactions:

The overall reaction can be summarized as follows:
