Question

Convert the following:

Propan-1-ol to 2-Bromopropanoic acid

Answer 1

Firstly Propan-1-ol is converted into propanoic acid by oxidizing in presence of alkaline KMnO₄ and then by using Red Phosphorous/NaOH and Bromine gas is further converted into 2-Bromopropanoic acid.

\[\begin{array}{cc}

\phantom{}\ce{CH3 - \underset{Propan-1-ol}{CH2 - CH2} - OH ->[alkaline KMnO4] CH3 - \underset{Propanoic acid}{CH2 - C - OH} + Br2 ->[red P][NaOH] CH3 - CH - COOH}\\

\phantom{.......................................................................}\ce{\underset{2-Bromopropanoic acid}{Br}}
\end{array}\]
