Used to work out the molecular of any member
3

5
Q
What is the test used to test for a carbon - carbon double bond
A
Bromine water and Alkenes
Shake an Allene with orange bromine water
The solution becomes colourless
This is because the broke molecules react with the alkene to make a dibroalkane which is colourless
6
