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

Answer»

addition of `H_(2)O` in presence of dil. `H_(2)SO_(4)`
addition of HCI followed by hydrolysis with `NaOH_("(aq)")`
oxymercuration-demercuration
hydroboration-oxidation reaction.

Solution :`underset("3-methylbut-1-ene")(CH_(3)-underset(CH_(3))underset(|)CH-CH=CH_(2)) underset((ii) H_(2)O_(2)//OH^(-))overset((i) B_(2)H_(6)//THF)to underset("3-methylbutane-1-ol")(CH_(3)-underset(CH_(3))underset(|)CH-CH_(2)-CH_(2)OH)`
This conversion requires anti-Markovnikov.s addition of `H_(2)O` and hence is possible only via hydroboration oxidation.
