The best method to prepare 3-methylbutane-2-ol from 3-methylbut-1-ene is

Options

A. addition of water in the presence of dil. `H_(2)SO_(4)`
B. addition of HBr in the presence of peroxide followed by reaction with dil. NaOH(aq)
C. hydroboration-oxidation reaction
D. oxymercuration-demercuration reaction

Answer

C

Explanation

In this conversion, anti-Markownikoff's addition of water is required and that too without any rearrangement. Therefore the best method in this case is hydroboration oxidation reaction.
