Q. Reaction of propene with diborane followed alkaline hydrolysis in the presence of hydrogen peroxide gives

AMUAMU 2012Alcohols Phenols and Ethers

Solution:

$CH _{3}- CH = CH _{2}+\left( H - BH _{2}\right)_{2} \rightarrow CH _{3}- CH _{2}- CH _{2} BH _{2} \xrightarrow{CH_3CH =CH_2}$
$\left( CH _{3}- CH _{2}- CH _{2}\right)_{2} BH \xrightarrow{ CH _{3} CH = CH _{2}}$
$\left( CH _{3} CH _{2} CH _{2}\right)_{3} B \xrightarrow[OH^-]{ H _{2} O , 3 H _{2} O _{2}}$
$\underset{\text { propan-1-ol }}{3 CH _{3} CH _{2} CH _{2} OH }+ B ( OH )_{3}$
