http://www.organicmystery.com/HaloGroup/PreparationFromAlcohol.php WebFeb 27, 2024 · The alkene hydrohalogenation reaction is an electrophilic addition reaction which converts alkenes into alkyl halides. The alkene reacts with a hydrogen halide (HX, where X is Cl, Br, or I), breaking the alkene π bond, adding a hydrogen to one alkene carbon, and adding a halogen atom (Cl, Br, or I) to the other.

WebAr – OH + HX → No reaction ii) The Reaction of Alcohols with Phosphorus halides (PX5 or PX3) This reaction helps in the formation of Chloroalkanes, bromoalkanes, and iodoalkanes. In this reaction phosphorus halides interchange the functional group of alcohols (–OH) with the corresponding halides. The reaction is as follows: WebIn the overall transformation a strong HX acid is converted to water, a very weak acid, so at least a stoichiometric quantity of HX is required for a complete conversion of alcohol to alkyl halide. The necessity of using equivalent quantities of very strong acids in this reaction limits its usefulness to simple alcohols of the kind shown above. eastern family resource center hours
