							Decolourizing Br2implies it is an unsaturated hydrocarbon. It adds up a single molecule of H2implies its an alkene. KMnO4oxidises alkenes to acid by breaking the double bond. Now, since asingle molecule of three carbon atoms is obtained, implies doble bond is present in the centre.
Hence alkene is hex-3-ene H3C-CH2-CH=CH-CH2-CH3
