Bromohydrin formation [Br2/H2O]
Bromohydrin Formation Definition:
Bromohydrin Formation Explained:
The intermediate bromonium ion is a high-energy intermediate and will react with any nucleophile that it encounters. When water is the solvent, it is more likely that the bromonium ion will be captured by a water molecule before having a chance to react with a bromide ion. So water will add to more substitute carbon by the SN2 mechanism. This leads to an anti-product and this means that will the bromine and the hydroxyl group will be on the opposite sides.
