EXPLAINING THE REACTION BETWEEN SYMMETRICAL ALKENES … WebChlorine, bromine or iodine can be added to an alkene. These reactions are usually spontaneous. Here are some examples: Ethene + chlorine → dichloroethane. Ethene + …
WebEthylene and Bromine. A classic test for alkenes is that they turn a brown aqueous solution of bromine colourless. Alkenes react with bromine to decolourize bromine water. … WebJul 7, 2014 · Best Answer. Copy.

WebOct 14, 2012 · Text-books will show how ethene interacts with bromine to form a cyclic bromonium cation, which with the liberated bromide anion makes for an ion-pair. Using quantum mechanics (DFT ωB97XT/6-311G (d,p)/SCRF=dichloromethane), one soon realises that the ion-pair will need to be stabilised, both by solvation and possibly by … 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.
