electrophilic addition - symmetrical alkenes and bromine

WebThis is an electrophilic addition reaction. The reagents are but-2-ene and cold liquid bromine (Br2) that is orange in colour. Br2 is very polarisable due to the large electron cloud of the Br atom. Thus, the electron dense pi bond (C=C) in the but-2-ene induces a dipole in the Br2, causing one end to be delta negative and one end to be delta ... WebAs bromine addition to ethene, propene and bromine reaction occurs in same way. First, Br 2 molecule is polarized by alkene bond.
