Oxymercuration demercuration reacti on i...

Oxymercuration demercuration reacti on is process of addition `H_2O` according to Markownikoff's rule without any rearrangement .
`CH_3 - CH = CH_2 underset(NaBH_4. overset(odot)OH)overset(Hg(OAc)_2 . H_2O) to CH_3 - underset(OH)underset(|)CH=CH_3`
Mechanism :
`Hg(OAc)_2 iffoverset(oplus)Hg(OAc) + Acoverset(odot)O`

Base `overset(Ɵ)OH` is used to neutralise `H^(oplus)` produced during the reaction :
Major product :

A

`Ph- underset(OH)underset(|)overset(CH_3)overset(|)C-CH_3`

B

`Ph-underset(OH)underset(|)overset(CH_3)overset(|)C-CH_2D`

C

`Ph- underset(D)underset(|)overset(CH_3)overset(|)C-CH_2-OH`

D

`Ph-underset(OD)underset(|)overset(CH_3)overset(|)C-CH_2D`

Text Solution

Verified by Experts

The correct Answer is:
B
`Ph-underset(OH)underset(|)overset(CH_3)overset(|)C-CH_2D`
