when an alkene is subjected to treatment with hg(oac)2 in water

by Prof. Ernie Turcotte V Published 2 years ago Updated 2 years ago

Hg (OAc)2, H2O 2. NABH, CH3 CH3 H2C H3C Acid-catalyzed addition of water to an alkene yields an alcohol with Markovnikov regiochemistry. The electrophilic H" adds to the sp carbon with the most hydrogens to yield the most stable carbocation intermediate, which then adds water to give the product alcohol.

When an alkene is subjected to treatment with hg OAc 2 in alcohol followed by reaction with NaBH4?

when an alkene is subjected to treatment with Hg(OAc)2 in alcohol, followed by reaction with NaBH4, what functional group is formed? C-D bonds are stronger than C-H bonds. kinetic effect is more profound.

When an alkene is treated with HG OAc 2 in etoh?

Description: When an alkene is treated with an alcohol in the presence of mercuric acetate [Hg(OAc)₂] it will add to the more substituted position of the alkene (Markovnikoff) to give an ether. The mercury can then be removed using NaBH₄.

What is oxymercuration and Demercuration?

In an oxymercuration–demercuration reaction, an alkene is treated with mercury(II) acetate, Hg(OAc)₂, and the product is treated with sodium borohydride. The net result is a Markovnikov addition product in which the OH group bonds to the more substituted carbon atom of the alkene.

What is syn addition?

Syn addition is the addition of two substituents to the same side (or face) of a double bond or triple bond, resulting in a decrease in bond order but an increase in number of substituents. Generally the substrate will be an alkene or alkyne.

Oxymercuration (H 2 O) Definition

Oxymercuration-demercuration is the reaction sequence in which mercuric acetate acts as the reagent. In the first step (oxymercuration), treatment of an alkene with this species in the presence of water leads to the corresponding addition product.

Oxymercuration (H 2 O) Explained

To understand this process, we must explore the reagents employed. The process begins when mercuric acetate, Hg (OAc) 2, dissociates to form a mercuric cation:
