Question

what happen when ethene react with bromine water. write reaction also plz

Answer 1

This is also called as an Unsaturation test. When Alkenes or Alkynes react with Bromine water they decolourise red Bromine thereby, giving an indication that they are unsaturated hydrocarbons.
The reaction is as follows.....
CH2=CH2 + Br2 ——CCl4——› Br-CH2-CH2-Br
The compound formed is known as 1,2 dibromoethane.
CCl4 dissolves Bromine in it forming Bromine water.
