Formation of Halohydrins (Addition of Hal2
and H2O to Alkenes)
Step 1: Electrophilic Addition
The one of the carbon atoms of the alkene donates the pair
of pi-bonding electrons to a bromine atom. In a concerted
process the bromine atom donates a lone pair of electrons back
to the other carbon of the alkene, and bromide anion departs.
Which of the following
three products is predicted from this flow
of electrons?
