Reaction of ethene with bromine
WebNov 1, 2010 · In 1925, Francis 1 showed that some chlorobromoethane is produced when aqueous bromine reacts with ethene in the presence of sodium chloride, indicating that the bromine is added to the double bond by slow electrophilic addition before the rapid addition of the chloride ion:. C 2 H 4 + Br 2 → C 2 H 4 Br + + Br- C 2 H 4 Br + + Cl - → C 2 H 4 BrCl . … 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.
