Solution
To prepare 3 - methylbutan - 2 - ol from 3-methylbut - 1 - ene shouls involve Markovnikov's addition of H – OH across double bond
(A) Addition of water in presence of dil. H2SO4 follows Markovnikov's addition of H – OH across the alkene
(B) Addition of HCL followed by reaction with dil. NaOH to an alkene can give substitution and elimination product after alkyl halide formation
(C) Hydroboration-oxidation reaction follows Anti-Markovnikov's addition of H – OH
(D) Reimer - Tiemann reaction.is a chemical reaction used for the ortho-formylation of phenols
Thus the best method to prepare 3-methylbutan-2-ol from 3-methylbut - 1 - ene is the addition of water in presence of dil. H2SO4.
