Answer:
Alcohol will be end product in any case.
Step-by-step explanation:
Alkenes are the class of organic compounds which are termed as unsaturated organic compounds. These compounds contain a single or multiple double bond depending upon the carbon chain length. The simplest alkene among many others is called Ethene with the molecular formula C2H4. Its molecular structure is H2C=CH2. The double bond present in any alkene serve as a nucleophilic component, meaning it will attack any element with partial positive to positive charge.
The process of introducing mercuric acetate to any alkene is termed as oxymercuration. This is a three step process. Please see the reference image.
As you can see there,
in first step, the double bond of an alkene attacks the mercury element which carries the positive, thereby dispositioning the acetate bond, and forming a cyclic mercury complex.
In second step, water acts as a nucleophile and attack on electrophilic (electron loving) carbon, which moves the bond towards mercury retaining mercury stability. In this step, oxygen of water molecule carries positive charge because of donating lone pair of electrons to the alkene carbon.
In third step, the acetate ion which left the mercury in first step, being a nucleophile attack the hydrogen of water molecule, donating the bonded pair to oxygen and restoring neutral charge over oxygen. It forms acetic acid which reconverts to mercuric acetate by subsequent reaction and therefore restores the catalyst.
If the first step, the oxymercurated compound is treated with Sodium Borohydride (NaBH4), the demercuration occurs leaving hydrogen at the same place where mercury was previously attached. It is termed as Oxymercuration-Reduction Reaction.It is a popular laboratory technique to achieve alkene hydration with Markovnikov selectivity while avoiding carbocation intermediates and thus the rearrangement which can lead to complex product mixtures.
