9.10: Formation of Halohydrins - Chemistry LibreTexts
2019年2月13日 · When the halogenation reaction of alkenes is performed in a nucleophilic solvent like water or alcohol, then the solvent becomes the nucleophile to give halohydrin or haloalkoxy products.
Halohydrin - Wikipedia
In organic chemistry a halohydrin (also a haloalcohol or β-halo alcohol) is a functional group in which a halogen and a hydroxyl are bonded to adjacent carbon atoms, which otherwise bear only hydrogen or hydrocarbyl groups (e.g. 2-chloroethanol, 3-chloropropane-1,2-diol). [1]
8.3: Halohydrins from Alkenes - Addition of HOX
Step 3 is a final acid-base step, where there is a loss of a proton from the oxygen to the solvent (water) to form the neutral halohydrin. In this case, a bromohydrin is the product of the addition reaction. To apply this mechanism we need to determine the electrophilic moiety in …
Halohydrins from Alkenes - Chemistry Steps
The Regiochemistry of Halohydrin Formation. Cyclohexene is a symmetrical alkene, and therefore, it does not matter what carbon of the halonium ion is attacked by water or other nucleophiles. However, for unsymmetrical akenes, different regioisomers can be formed depending on which carbon is attacked. ...

2013年3月15日 · A halohydrin is a molecule containing C-OH and C-halogen bonds on adjacent carbons. The reaction also proceeds through a halonium ion intermediate. As with halogenation, anti- addition products are formed exclusively.
8.3 Halohydrins from Alkenes: Addition of HO-X - OpenStax
Another example of an electrophilic addition is the reaction an alkene with either Br 2 or Cl 2 in the presence of water to yield a 1,2-halo alcohol, called a halohydrin.

Halohydrin - Synthesis, Regioselectivity, Reactions and …
Halohydrin is a functional group in which hydroxyl and halogen groups are bonded to adjacent carbon atoms. Halohydrins are categorised as fluorohydrins, chlorohydrins, bromohydrins or iodohydrins, depending on the halogen present.
Halohydrin formation (video) | Khan Academy
Reaction of an alkene with a diatomic halogen and water, converting the double bond to a single bond with halogen and hydroxyl substituents.
Halohydrin Formation – Alkene Reaction Mechanism - Leah4Sci
Reaction Overview: The Halohydrin formation reaction involves breaking a pi bond and creating a halohydrin in its place. Halo = halogen and Hydrin = OH.
