Answer--
C2H5OH + 2[O] in presence of alkaline KMnO4 gives CH3COOH + H2
oxidation reaction will occur when 5% of alkaline potassium permaganate is added to the ethanol. the name of the compound formed is ethanoic acid(acetic acid). we can perform the process of esterification to identify this compound.
When 5% alkaline potassium permanganate solution is added drop by drop to propanol taken in the test tube, then its purple colour disappears as it oxidizes the propanol to its respective carboxylic acid i.e. propanoic acid.
It is because alkaline potassium permanganate is known to be a strong oxidizing agent , which oxidizes the primary alcohol- propanol to propanal and then finally to propanoic acid.
Chemical equation:
alk. KMnO4
CH3CH3CH2OH ----->CH3CH3CH2COOH
