Question

Reaction of bromine dissolved in Carbone tetrachloride?
​

Answer 1

Answer:

H − C∣H = C∣H −H

(i) Compound A is ethene.

(ii) Brown colour of bromine is discharged. It serves as a test for unsaturation.

Answer 2

Explanation:

Bromine dissolved in carbon tetrachloride is decolorized when added to ethene. What causes this reaction?

Well, first off, be careful with liquid bromine; it is one of the most corrosive substances in the lab, and can cause horrendous burns… Bromine is a non-polar, covalently bound molecule that has some solubility in non-polar solvents (and it also has some solubility in water)..and thus in carbon tet, bromine is dissolved..

On the other hand, when bromine is treated with ethylene, the halogen REACTS according to the following expression…

H2C=CH2+Br2→BrH2C−CH2Br

Caramel-coloured bromine becomes COLOURLESS dibromoethane
