electrophilic addition by Br2 forms a dibromoalkane
how is a dipole induce in a Br-Br bond in electrophilic addition?
the electronrich carbon double bond induces a dipole in Br2 forming delta positive and negative Br. the delta positive Br forms attraction to the e- in the double bond.
markpoints for electrophilic addition by Br2
m1: curly arrow from double bond to the delta positive Br
m2: curly arrow from bond between Br2 to show bond breaking
m3: carbocationintermediate on newly formed halogenoalkane and curly arrow from middle of e- on Br- to carbocationintermediate
If Br2 is added to an unsymmetrical alkene in electrophilic addition it forms oneproduct
if Br2 is added to a symmetrical alkene in electrophilic addition it forms oneproduct
