The compounds that can decolourise bromine water are:

(2) CH2=CH2

(4) CH3-CH=CH2

- Bromine water is a coloured compound that can be decolourised by alkenes.

- It is also used as a test for unsaturation.

- Here, (1) is a carboxylic acid, (2) is an alkene, (3) is an alkane and (4) is also an alkene.

- So, only (2) and (4) will decolourise the bromine water.
