Q.
Identify an appropriate reagent for the conversion of alcohol to carboxylic acid.
Alcohols Phenols and Ethers
Solution:
$RCH _{2} OH \xrightarrow[(O)]{\text { Oxidation }} \underset{\text{Aldehyde}}{RCHO} \longrightarrow \underset{\text{Carboxylic acid}}{R COOH}$
Strong oxidising agents such as acidified $KMnO _{4}$ are used for getting carboxylic acids from alcohols directly.
