Red colour
by adding bromine water to the compound. if it is unsaturated, the red colour of the bromine water will fade quickly. if it is saturated, then it will not fade.
No!! Benzene wont de colourise bromine water although it is an unsaturated compound ,as it is an aromatic compound and it does not undergo addition reaction.
Bromine water is a dilute solution of bromine that is normally orange-brown in colour, but becomes colourless when shaken with an alkene. Alkenes can decolourise bromine water, while alkanes cannot.
To distinguish between primary alkylamine and primary arylamine, reaction with aqueous bromine (Bromine water, Br2) can be carry out. There will be a formation of 2,4,6-tribromophenylamine which seen as white precipitate. Also, colour of bromine colour will be decolourized.

Bromine water and NaCl mixed together appears colourless. The only condition which there is a colour is when the bromine water is old (bromine water is basically rum), but under normal conditions, the mixture ought to be colourless.
There is no colour change
It goes red
Kind of Red/Brown, or rust color, but vibrant.
As polyehtene is unsaturated(single bond) it does not react with bromine and there is no colour change.But bromine reacts with ethene and it becomes colourless.

it changes colour form orangy-brown to colourless
