Question

Propene can be converted into propan-1-ol by:

Options

• Addition of O₃ followed by hydrolysis

• B₂H₆/H₂O₂/OH^-

• Addition of HBr in presence of peroxide followed by hydrolysis.

• All these methods

Answer 1

Propene can be converted into propan-1-ol by:

B₂H₆/H₂O₂/OH^-

Addition of HBr in presence of peroxide followed by hydrolysis.

Explanation:

Hydroboration oxidation reaction gives alcohol against Markovnikov's rule.

\phantom{}\ce{\underset{}{CH3 - CH = CH2} ->[B2H6/THF][(ii) H2O2/OH-] \underset{}{CH3 - CH2 - CH2-OH}}\\
\end{array}\]

\[\begin{array}{cc}
\phantom{}\ce{\underset{}{CH3 - CH = CH2} ->[HBr][Peroxide] \underset{}{CH3 - CH2 - CH2-Br}->[Hydrolysis] \underset{}{CH3 - CH2 - CH2-OH}}\\
