Describe the C=C double bond in ethene?
It is a region of high concentration of negative charge
What are in ethene is an area of negative charge?
The C=C double bond
What happens when the Br2 molecule approaches the C=C double bond?
It becomes polarises as a result of repulsion by the electrons in the double bond
Why does the Br2 molecule become polarised?
As a result of repulsion by the electrons in the double bond
What do the electrons in the double bond cause to happen?
They cause the Br2 molecule to become polarised as it approached the bond
List the events that happen during stage one, polarisation. 3
Bromine molecule approaches ethene As bromine nears the highly negative C=C double bond of ethene it becomes polarised The bromine molecule is polarised as a result of repulsion by the electrons in the double bond
