Question

Explain the mechanism of the bromination of ethene without using the quantum mechanical model of an atom.

Answer 1

H2-C=C-H2 is ethene molecule. When it reacts with Br2(bromine).The double bond breaks, and a bromine atom becomes attached to each carbon. The bromine loses its original red-brown colour to give a colourless liquid. In this case of the reaction with ethene, 1,2-dibromoethane
(BrH-C-C-BrH) is formed
