what is the observation when bromine water is added to alkene? I know that it will give a positive reaction under the exposure of the sunlight, but i'm not so sure about the colour that will be observe. Will the brown colour of bromine will be decolourise or polarize? What is the exact different between polarize and depolarize?

If you add bromine to an unsaturated hydrocarbon, the bromine will add across the double bond, forming a di-bromo compound. The solution will change from red-brown to colorless as the bromine is consumed.
Polarization of light occurs when the normally random orientation of electromagnetic energy becomes aligned. You can detect polarized light using a polarized lens -- one that will only allow a certain orientation of light to pass. As you rotate the polarized lens, the target will appear to grow darker and then lighter as you rotate through 180°. It will be darkest when the polarizing lens is at right angles (90°) to the orientation of the polarized light source.
