AQA Chemistry. Organic chemistry. Alkenes. Addition reactions of alkenes. The use of bromine to test for ... WebEthene is an symmetrical alkene with two carbon atoms. With HBr, ethene readily reacts and give ethyl bromide (bromoethane) as the product. CH 2 =CH 2 + HBr → CH 3 CH 2 Br HBr molecule is added across the double bond of ethene. In this case, Markovnikov rule is not required because ethene molecule is symmetrical around the double bond.
