For breaking alkenes, liquid bromine was utilized. When liquid bromine is added to the finished product and it turns clear, it has reacted.
The principal test used to determine the organic compound's unsaturation in a qualitative examination of organic compounds is the bromine water test. It aids in determining the compound's functional group.
Unsaturated hydrocarbons and bromine water engage in an additional process. When the double bond breaks, bromine is added. The reaction's final result has no color.
However, there is no addition reaction when bromine water combines with saturated hydrocarbons. As a result, the solution's hue is unchanged and remains brown.
So, a qualitative test for saturated and unsaturated hydrocarbons is a reaction with liquid bromine.
The presence of unsaturated hydrocarbons, or functional groups with double bonds, can be seen in the mixture when it transforms into a clear
