... The bromine molecule is polarised i.e it has a δ+ and a δ- atom like when the bond is polar. This happens because the electrons in the Br 2 molecule are repelled by the electrons in the C=C. The Brδ+ end now acts as an electrophile. Electrophiles are attracted to a negatively charged region (the C=C ...
