Bromine Addition to Water
The reaction of bromine with water is an electrophilic addition reaction. The bromine molecule adds to the double bond of the water molecule, forming a bromonium ion intermediate. The bromonium ion then reacts with water to form the final product, 2-bromoethanol.
The mechanism of the reaction is as follows:
- Bromine adds to the double bond of the water molecule, forming a bromonium ion intermediate.
- The bromonium ion intermediate reacts with water to form the final product, 2-bromoethanol.
The reaction is regiospecific, meaning that the bromine atom adds to the carbon atom that is most substituted. This is because the more substituted carbon atom is more stable.
Other alkenes that undergo similar reactions include ethylene, propylene, and butene.
Product Identification
The major product of the reaction is 2-bromoethanol.
The reasons for the formation of the major product are as follows:
