Answer:
[tex]BH_{3}[/tex] followed by [tex]NaOH/H_{2}O_{2}[/tex] is used for the given conversion.
Explanation:
Hydroboration of 1-decene is done first. Here [tex]BH_{2}[/tex] group adds onto less hindered side due to steric reason.
Then hydrolysis is done to replace [tex]BH_{3}[/tex] by OH group. This hydrolysis process is usually done by using [tex]NaOH/H_{2}O_{2}[/tex].
[tex]LiAlH_{4}[/tex] or [tex]NaBH_{4}[/tex] does not reduce double bonds.
Also hydrolysis of alkyne bond is generally done by using [tex]HgSO_{4}/H_{2}SO_{4}[/tex].
[tex]Br_{2}/H_{2}O[/tex] reacts with double bond to produce bromo susbstituted alcohol.
