Halogenation of Alkenes - Chemistry Steps
WebStep 1- Halohydration. The alkene acts as a nucleophile and attacks the X2, which simultaneously results in the lone pair on the X attacking the edge of the alkene, forming a 3 membered ring ... Extra lone pair on oxygen moves down, resulting in a double bond and elimination of an OH, by an E1cb mechanisms Forms alpha-beta unsaturated carbonyl ... WebAlkynes are unsaturated hydrocarbons with a tripe bond (C≡C) The active site in alkenes is the double bond. The active site in alkynes is the triple bond. The elements of Group 17 are known as halogens. Fluorine (F), chlorine (Cl), bromine (Br) and iodine (I) are halogens. Unsaturated hydrocarbons (alkenes and alkynes) react with hydrogen ...
