WebIn fact, bromine is a very polarisable molecule - in other words, the electrons in the bond are very easily pushed to one end or the other. As the bromine molecule approaches the ethene, the electrons in the pi bond tend to repel the electrons in the bromine-bromine bond, leaving the nearer bromine slightly positive and the further one slightly negative. WebWhat does ethene and bromine form? Ethene and bromine reaction Ethene reacts with liquid bromine to give 1,2-dibromoethane. Ethene and bromine reaction also gives a symmetrical alkyl halide compound. Two bromine atoms are attached to the two carbon atoms in the ethene molecule. What does Bromo mean in organic chemistry?
