The reaction which involves the conversion of ethanoic acid from ethanol is an oxidation reaction.
When ethanol $\left({\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}\right)$ undergoes oxidation, it forms ethanoic acid$\left({\mathrm{CH}}_3\mathrm{COOH}\right)$. This reaction takes place in the presence of a strong oxidising agent like KMnO₄. A well-balanced reaction for the same is as follows:
${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH} \underset{{\mathrm{KMnO}}_4}{\overset{\left[\mathrm{O}\right]}{\to }} {\mathrm{CH}}_3\mathrm{COOH}$
