The reaction of bromine with an alkene such as cyclopentene is a good laboratory test for the presence of a double bond in a compound.What type of reaction is it?

Question

Quizplus · Accepted Answer

The reaction of bromine with an alkene such as cyclopentene is an example of addition reaction, where two molecules combine to form a single product. In this case, the double bond of cyclopentene is broken and two bromine atoms are added to the molecule, resulting in the formation of 1,2-dibromocyclopentane. This test is based on the ability of bromine to decolorize in the presence of an alkene due to the addition reaction. Thus, the correct answer is A, addition.
