Mercuration of alkenes
In organic chemistry, the oxymercuration reaction is an electrophilic addition reaction that transforms an alkene (R2C=CR2) into a neutral alcohol. In oxymercuration, the alkene reacts with mercuric acetate (AcO−Hg−OAc) in aqueous solution to yield the addition of an acetoxymercury (−HgOAc) group and a hydroxy (−OH) group across the double bond. Carbocations are not formed in t… WebExplanation: Alkenes do not undergo mercuration, indeed they undergo oxymercuration , a process in which an alkene is converted into an alcohol. 5. Identify the incorrect statement regarding the synthesis of alkenes a) Cracking of a hydrocarbon yields alkenes b) The reactions are exothermic c) Zeolite catalyst helps in the synthesis of alkenes

WebMercuration reaction with Pd(II) compounds coordinate to alkenes to form rr-complexes. Roughly, a decrease in the electron density of alkenes by coordination to electrophilic Pd(II) permits attack by various nucleophiles on the coordinated alkenes.In contrast, electrophilic attack is commonly observed with uncomplexed alkenes. The attack of nucleophiles with … WebThis organic chemistry video tutorial provides a basic introduction into the alkoxymercuration demercuration reaction mechanism of alkenes into ethers.Alkene...
