Quizplus · Accepted Answer

The reaction of bromine with an alkene such as cyclopentene is an example of an addition reaction, where the bromine adds across the double bond of the alkene molecule. This reaction is a good laboratory test for the presence of a double bond in a compound because if there is no double bond present, the reaction will not occur.
