Propene is unsaturated.

Explanation:

Propane is a saturated hydrocarbon meaning it has all single bonds. Propene is unsaturated and has one carbon to carbon double bond. This is a reactive centre and can undergo electrophilic addition reaction. It does so with #Br_2# to form 1,2-dibromopropane, which is saturated and decolourises bromine.

The reaction with bromine is a standard test for distinguishing between a saturated alkane and an unsaturated Alkene.
