Question

$Propan-1-ol$ can be prepared from propene by

• A. $H _{2} O / H _{2} SO _{4}$
• B. $Hg ( OAc )_{2} / H _{2} O$ followed by $NaBH _{4}$
• C. $B _{2} H _{6}$ followed by $H _{2} O _{2}$
• D. $CH _{3} CO _{2} H / H _{2} SO _{4}$

Answer 1

Answer: (C)

Hydroboration yields 1° alcohol from alkenes.
$\underset{\text{Propene}}{3CH_3CH = CH_2}\xrightarrow [THF]{BH_3 \, in} \underset{\text{Tripropyl borane}}{(CH_3CH_2CH_2)_3B} \xrightarrow[OH^-]{3H_2O_2} \underset{\text{Propan-1-ol}}{3CH_3CH_2CH_2OH + B(OH)_3 } $
