A hydrohalogenation reaction is the electrophilic addition of hydrogen halides like hydrogen chloride or hydrogen bromide to alkenes to yield the corresponding haloalkanes. [ 1 ] [ 2 ] [ 3 ] If the two carbon atoms at the double bond are linked to a different number of hydrogen atoms, the halogen is found preferentially at the carbon with fewer ...
Can occur either in syn or anti addition fashion, depending on the solution it is in; 50% of each orientation. This reaction is considered Markovnikov because the halogen substituent attaches to the more substituted carbon. Hydration: Can occur either in syn or anti addition fashion, depending on the solution it is in; 50% of each orientation.
As solutions in non-aqueous solvents, such as acetonitrile, the hydrogen halides are only modestly acidic however. Similarly, the hydrogen halides react with ammonia (and other bases), forming ammonium halides: HX + NH 3 → NH 4 X. In organic chemistry, the hydrohalogenation reaction is used to prepare halocarbons
Thermodynamic and kinetic controlled products of hydrohalogenation of alkynes through vinyl cation intermediate. Adapted from [25] In the hydrohalogenation of phenylpropene, two distinct alkene products are formed because of thermodynamic and kinetic effects. The linear sp-hybridized vinyl cation may be attacked by the halogen from two directions.
Hydrogen iodide (HI) is a diatomic molecule and hydrogen halide. Aqueous solutions of HI are known as hydroiodic acid or hydriodic acid, a strong acid.Hydrogen iodide and hydroiodic acid are, however, different in that the former is a gas under standard conditions, whereas the other is an aqueous solution of the gas.
In chemistry, halogenation is a chemical reaction which introduces one or more halogens into a chemical compound. Halide-containing compounds are pervasive, making this type of transformation important, e.g. in the production of polymers, drugs. [1]
