1,2 dibromoethane and 1-bromo, 2-chloro ethane and 2-bromo ethanol
Chlorine displaces bromine as it is more reactive, and it creates sodium chloride aqueous and bromine aqueous.
2I- + Br2 ---> I2 + 2Br-
Chlorine is more reactive than bromine thus bromine is unable to displace chlorine to form potassium bromide.
Chlorine is a stronger oxidizer than elemental Bromine. So, when yellowish chlorine gas is bubbled through the Bromide solution, a red colour is formed which is Bromine. Chlorine oxidizes Bromide ions to elemental Bromine while itself is reduced to Chloride ions. So, the total reaction is: Cl2 + Br- ----> Br2 + Cl-
When a solution of sodium bromide is added to an acidified solution of Sodium bromate , bromine is liberated as given below: 6H+ + 5 Br- + BrO3- --> 3 Br2 + 3H2O When a solution of sodium bromide is added to an acidified solution of Potassium bromate , bromine is liberated as given below: 6H+ + 5 Br- + BrO3- --> 3 Br2 + 3H2O In the presence of acid, sodium and potassium ions have no effect on the rate of reaction (ref: Arthur I.

The alkyne reacts with bromine removing it from the aqueous solution.
The bromine test (discoloration) is valid for compounds with double or triple bonds between carbon atoms and for phenols. This is a simple and common experiment.
